mailman/ ta the coolest member of the family?

my kids call chaim g the mailman. im not sure why. any suggestions. also you have to hear rumbles say chaim g, its very cute. chavi came home from camp yesterday all exctied. apparently there was a hatzalah call some where along the way to camp and she only wanted to call ta and tell him. yos, who was standing near by asked "why does zaidy drive a police car?". i guess ta is much cooler then we all thought.
