The funniest (and most disgusting) sex acts no one has ever done

This is probably the most famous sex act that everyone giggles about but no one has ever done.

The Dirty Sanchez is a time honored event in which one partner inserts a finger into the anus of the other, pulls out fecal matter, and wipes it across the upper lip of the partner. This is said to make the partner look like someone whose name is Dirty Sanchez.

The Angry Dragon describes the act of ejaculating into a partner's mouth and then smacking the back of his or her head in an attempt to make the ejaculate come out of the nose, simulating the smoke that comes out of a dragon's nose. And, presumably, if one did this the partner would certainly be angry.

A Brown Necktie is achieved when, after performing anal sex on a woman, the partner rubs his penis between her breasts, leaving a brown stain.

The Cleveland Steamer describes the act of defecating on a partner's chest.

Finally, an entry that doesn't involve fecal matter!

Couch Bombing is spuposedly the age-old act of filling a ziploc bag with shortening or some other similarly squishy substance, placing it between couch cushions, and...umm...humping said bag. As Rotten.com puts it, ""no need to buy it dinner first."

Another famous one, the Donkey Punch is when one partner is performing anal sex from behind and punches the receiving partner in the back of the head, supposedly creating pleasurable anal contractions.

This is the entry on the list that has probably actually been done by many mischievous partners, but it's still funny. The Dutch Oven is the act of farting under the covers and then holding them over your partner's head, trapping them in with the presumed stench.

Come on, you know you've done it!

The Hole In One is the unlikely act of a man sticking his penis in his own anus.

The Hot Lunch describes the act of defecating into a partner's mouth.
