Quote from Tim in Reality Bytes
Al: Now, this is Ken Bowersox. He is a Navy man, just like me, and his friends here nicknamed him Sox. Tim: I suppose you got that nickname because up in space you never change your socks? Hoo, boy! Ken Bowersox: No, Tim, they call me that because my last name is Bower...sox. Tim: Well, they could call you Bower. Ken Bowersox: They don't.
