Late at night this guy runs into a pub and gets a glass of water from the bartender. The guy drinks it in one gulp then asks for a second glass. Six glasses later, and he has recovered enough to speak.

"Thanks," he gasps.

"That's one hell of a thirst you've got," says the bartender.

The guy says, "Any man would be as bad if they'd just had sex with the woman in my car. She's insatiable. She wants me to go right back out there and do it all again, but I can't."

"Where's your car?" the bartender asks.

"At the roadside," the guy gasps.

"Tell you what," says the bartender, "you watch the bar for me while I go out and take your place."

"Be my guest, the broad's a nympo. She'll do anybody."

So the bartender goes outside and gets in the car. It's totally dark, so the woman doesn't realize she's with a different man. They get right down to it, humping away. Five minutes later there's a knock on the window. It's a cop and he shines his flashlight on the naked couple.

"What's going on here?" he asks.

"It's all right, officer," explains the bartender. "She's my wife."

"Oh, sorry sir, I didn't realize..."

"Neither did I till you switched on that damned light."
