Really funny gross-out moments (blood, poop, pee, etc.) in movies/TV!

[retrorussell]

Hey all,
What funny gross-out moments can you contribute?
These can be intended to be serious but really strike you as funny, or were intended to be sophomoric but as an adult you still find it funny.  And pretty gross.. involving usually bodily fluid/waste.

A few:
This isn't terribly gross but it cracked me up.  In UHF Weird Al is an annoying kids' show host.  He addresses a bored kid in the audience:
Al: "Hi!  What's your name??"
Kid: "Billy."
Al: "Billy what?"
(boy spits a BIG OLD LOOGIE on Al's nose)
This put me in stitches and I still laugh thinking about it today.

I admit I haven't seen the rest of this movie-- it's probably not very good-- but the poop scene is so gross and funny to me!  The teacher gets COATED in the face!  Yuck!

My personal favorite! Nothing in movie history has ever topped this genius comedy gag. Ever.

in Bridesmaids (2011) when Maya Rudolph's character takes a poop on the street after eating bad food. I thought that was hilarious.

DEAD ALIVE dinner scene!
A zombifying woman squirts a wound into a bowl of custard and a guy eats it!
Then her ear falls into her custard and she eats it!
Intended to be hilarious and it succeeds beautifully!
