Spanish Fly
A guy offers to buy a drink for an attractive young woman seated at a bar.
She gives him the green light, so he goes to the end of the bar and whispers to the bartender to make up a Martini for her and to put some Spanish-fly in the drink.
The bartender whispers back to say he's all out of Spanish-fly and all he has left is Jewish-fly.
Shrugging his shoulders, the guy says, OK, put some of that in her drink.
As she sips on the drink, she gets more and more cozy, really warming up to the guy.
Finally, she finishes the drink, leans over and whispers in his ear. 'Let's go shopping.'
