Here's your reward for scrolling through all those pictures of useless junk!
A guy goes into a restaurant with his shirt open at the collar, and is stopped by a bouncer. "Hey guy, look around! This is an extremely classy place. No one gets in without a necktie!"
So the guy goes out to his car and he looks around for a tie and discovers that he just doesn't have a one. But as luck would have it, he sees a set of jumper cables in the trunk. In desperation, he ties these around his neck, and manages to fashion a decent looking knot and lets the ends dangle free.
He heads back to the restaurant. The bouncer looks him over for a moment with suspicious, and then says, "Well, okay, I guess you can come in. But you better not try to start anything."
