Shamelessly copied from Rabbi Mendy Uminer’s weekly email, joke of the week:
Polite Israeli's
Benny is on his way to Saint Barts for a 2 week vacation. As he’s waiting in the departure lounge at Heathrow airport, a gorgeous woman walks over and sits down next to him.
Benny is convinced that she must be an airline stewardess. However, because she’s not in uniform, he doesn’t know which airline. So he attempts to find out without asking her directly.
He turns to her and chants aloud the Delta Airlines slogan, "Love to fly and it shows?"
She just stares at him in a confused kind of way, so he’s sure she doesn’t work for Delta Airlines.
He turns to her again and this time chants aloud the Singapore Airlines slogan, "Something special in the air?"
Once again she gives him the same confused look, so he’s sure she doesn’t work for Singapore Airlines.
Benny then turns to her for a third time and chants aloud the Thai Airways slogan, "Smooth as Silk?"
At this, the woman gets very, very angry. With a snarl on her face she turns to Benny and shouts, "What the hell do you want?"
Suddenly, all is clear to Benny - he knows who she works for. He slumps back in his chair and says, "Ah, so you work for El Al."
