Deadhead Zeke was seeing a show out of town, and was going to crash at his pal Cosmo’s place.
However, Zeke missed Cosmo after the show, and was feeling pretty lost and disoriented.
So he called Cosmo asking how to get to his pad. Cosmo told him to look at a street sign to find out where he was, and he would go pick him up.
Zeke looks at the street and says, "I’m at the intersection of Walk, Don’t Walk".
Cosmo replies "Dude! that’s right outside my building!"
