Kramer: [answers Jerry's phone] Hello. What-delay Industries?
Elaine: No, no...
George: [o.s.] Vandelay. Say Vandelay!
Kramer: No, you're way, way, way off. Well, yeah, that's the right number but this is an apartment.
George: [runs from the bathroom] Vandelay! Say- [trips] Vandelay Industries!
Kramer: No problem. No problem. [hangs up] How did you know who that was?
[Jerry returns and finds George, with his pants around his leg, lying on the floor]
Jerry: And you want to be my latex salesman.
