Since I no longer receive many humor emails from one of my favorite sources *ehem* I had to dig way back into the "fun files" archives for something really good. This was written by my former "source of sheer entertainment" who must remain nameless--unless she wishes to come forth.
Whoooo is the son of God? Whoooo?

Celebrity Nativity at Madame Tussauds
I know when I think of the Virgin Mary, Posh Spice is the first person who comes to mind. And that's Hugh Grant as a shepherd, next to Samuel L. Jackson.
Weird and Unnerving
They're, um, naked. Naked little trolls.
Savior under glass
We will look at some examples of strange nativity waterglobes.
Bethlehem air traffic control didn't know what to do about the people floating above the city.
Here's another example of the hermetically sealed Baby Jesus concept. The waterglobe part rotates. Of course it does.
The Messiah in the bubble
"So, as you can see, it wasn't really a normal delivery. Do you think you can get him out?"
They tried to be cheerful, but they knew the spider would return soon.

The huge snowman angel is frightening.

Maybe santa is bringing baby Jesus a nice refreshing Coca-Cola

Who stole the cookie from the deeply confused cookie jar?

I'm imagining the design meeting on this one.
"Rainbow! There's a rainbow in the Bible. You know, Noah? Let's put a rainbow in there."
"Wasn't Joseph, like, really old when Jesus was born?"
"You're thinking of Abraham. He was old when Isaac when born, and then there was the whole sacrifice thing..."
"Look, I've already made his hair gray, so you're just going to have to deal with it."
"Is that a bottle in his hand?"
"NO. That's a lantern."
"Are you sure? 'Cause it looks like a bottle. Whoo hoo! Toasting the birth of the Christ child!"
"It's. A. Lamp."
"Maybe the wise men brought booze for the new dad. That was so thoughtful. It's definitely a bottle."
"SHUT IT! It's a LAMP! I hate you." [flounces out]
It's Christmas...in the village of the damned Proof that there is something worse than Pweshus Moments. And that's...knockoffs with seriously deranged lipliner.
Yummmmmmmm 
Is the baby Jesus made from mini marshmallows and those little Andes tingaling mints? And his name shall mean, Snacks Are With Us.
Crap, now I want a S'more. And I don't even really like S'mores.
I feel like chicken tonight
Chicken nativity! *b'gock*
I would really have to display this one in a creche made from a KFC bucket.
Can't sleep...Joseph will eat me...
Yes, it's a gianormous inflatable holy family.
of course it lights up.
CSI: Bethlehem
Both adults appeared to be missing their legs. 
I'm a Parade Float
That's some sparkle. There's a wise man on the back, presumably lost and trying to find his way back to the front.
"I think your robe is FAAAAB-u-lous!"
Is there any more beautiful combination of words in the English language than glitter nativity?
I actually bought this one on ebay, and will have it soon. It will sit under my aluminum tree and be so very festive. I love this.
The Holy Family of Kitsch
This is a set of costumes for those geese people have on their porches, the ones that get dressed up to match the current holiday or season. Those geese. The best detail is of course the baby Jesus. Since I guess there are no cement/resin/plastic baby ducklings available, well, rubber ducky, you're the one.
Lo, I have come to make bathtime so much fun!
"All I'm saying is, you could think about changing a diaper once in a while!"
(Mary looks really pissed off here.)

Doggie Nativity--both live and imaginary!
Disco Holy Family!
In the future, holiness will be designated by fiber optics. It's true!
The person whose soul-crushing job it is to write product descriptions for this stuff says it best:
This colorful 14” fiber optic nativity is a must have for your Christmas décor. Exquisitely crafted from porcelain and masterfully accented with hand painted details, this beautiful nativity contains transparent fibers that continuously change through a rainbow of colors.
Got that? It's exquisitely crafted. Those details are masterful!
Once again proving that the only thing better than a cheap nativity is a cheap nativity with fiber optic holiness-indicators:
I think everyone looks a little cramped in there for some reason. Joseph looks like his feet hurt. That star is just kind of crammed onto the roof, there's a random pillar in there, and everyone has to hold their heads at weird angles to see the child. I kind of feel sorry for them.
This is a very depressing nativity, and the fiber optics only make it worse. It's trying too hard.
Nativity Bake Set
I don't know about you, but I never want to have to decide if I should eat the baby Jesus feet-first or head-first.

And where would you keep your tasty creche-o-licious treats?
How about here:

mmmmm...savior-licious
Chocolate Nativity
Research suggests that cats actually hate being dressed up.

Is this the Bible Belt? (ba-dum-bum)
The problem with most of the nativities I've posted so far is that you can't really take them with you. Only a select few people will ever know about the glory of your nativity collection...unless! You get this amazing nativity belt buckle.

This was on ebay. It's a nightlight.
Those are aliens, right? Back in the window?
Hey kids! Come throw beanbags at the holy family! Yeah!

I thought everyone could use a lesson on Bad Nativities... Because I care!
I hope you enjoyed the Cavalcade of Bad Nativities
