I actually know a good joke about White Russians. But it can come across as a bit racist, so I don't tell it unless I'm sure it's to one of these "you can laugh at anything!" guys, and not someone who takes things way too seriously.
Oh, what the hell...
A redneck walks into a bar and sits down. The first thing he notices is the bartender is a black dude, and he can't stand blacks! He won't even speak to the guy. So he waves over a waitress. "Young lady, you tell this coon to fix me a White Russian. But tell him to wear some gloves. I don't want his filthy hands all over my drink." The bartender says, "tell the gentleman I have to get some gloves from the back. Might take a few minutes to find them."
So the bartender goes in the back, grabs a pair of gloves and rubs his dick all over them. Then he returns to the bar, mixes the drink, and the redneck drinks it down solid. He calls the waitress back over. "Lady, that was pretty good! You tell this old coon to fix me another! But remember, he'd better be wearing some gloves!" Bartender says to her, "tell him I'm going to get some clean gloves. Be back in a few minutes."
He goes in the back, grabs a new pair of gloves, rubs them all over his dick, and 'finishes' on them this time. He walks out to the bar, mixes the drink, the redneck swallows it down. He calls the waitress back over to pay her and says, "I'm not sure what it was, but that was the best damn White Russian I've ever had in my life!" The bartender says, "tell the gentleman that not all Russians are white. Some of 'em have a black daddy!"
