It’s not THAT funny...... :^)
OK maybe it is!!
What would have been funnier is if they had gotten stuck in their compromising position, maybe collapsed unconscious from their drinking bout coupled (sic) with excess “stimulation”... and had to be pried apart by police.
There was a joke that went something like that. A drunk stumbles up to a whorehouse door and knocks. The madam comes to the door, takes one look at him and says, "Get out of here. We don't cater to drunks." The drunk pulls out a thousand bucks and says, "Oh yeah? For a thousand bucks you'll do it on top of the roof." The madam says, "Are you crazy, it's freezing cold up there!" But avarice gets the better of her, and she accedes to his request. They go up to the top of the roof and start getting it on. A few minutes later, they freeze solid, and their momentum sends them crashing down to the street below.
A few minutes later a second drunk comes by and sees them lying there, frozen solid in a compromising position. He knocks on the door, and a prostitute answers. "Get out of here," she says, "we don't cater to drunks."
"Oh, but you got me all wrong!" slurs the second drunk. "I just wanted to tell you that your sign fell down!"
