A woman and her boyfriend are out having a few drinks. While they're sitting there having a good time together, she starts talking about this really great new drink.

The more she talks about it, the more excited she gets, and starts trying to talk her boyfriend into having one.

After a while, he gives in and lets her order the drink for him.

The bartender brings the drink and puts the following on the bar: a saltshaker, a shot of Baileys, and a shot of lime juice.

The boyfriend looks at the items quizzically and the woman explains.

"First you put a bit of the salt on your tongue, next you drink the shot of Baileys and hold it in your mouth, and, finally, you drink the lime juice."

The boyfriend, trying to go along and please her, goes for it. He puts the salt on his tongue -- salty, but OK.

He drinks the shot of Baileys - smooth, rich, cool, very pleasant. He thinks, "This is OK'.

Finally, he picks up the lime juice and drinks it.

.... In one second the sharp lime taste hits...

.... At two seconds the Baileys curdles

.... At three seconds the salty curdled bitter taste hits.

This triggers his gag reflex but being manly, and not wanting to disappoint his girlfriend, he swallows the now nasty drink.

When he, finally, chokes it down, he turns to his girlfriend and says, "Jesus, what do you call that drink?"

She smiles widely at him and says............
"Blow Job Revenge"

:o  

I've had a variation on that, campari and Bailys mixed in a shot glass.  Called a monkey brain if I remember rightly.

The other one I haven't tried is a raw egg in a pint of Guiness which is supposed to float undetected below the head and cause gagging.
