Ex-Bus Boy

But no longer on the

travelling back and forth between Waterloo and Toronto.
I saw a guy, on a Greyhound bus, working on a laptop, talking on a cell phone. On a Greyhound bus. So I said to him "Hey, buddy, could you, ah, pick an income level?"
-- Comedian Mike Royce on Late Night with Conan O'Brien, November 26, 1998
Actually - I've taken my last trip on the bus, Wednesday June 9, 1999. The bus overheated and stalled. Took two and a half hours. Gonna miss that commute.

Personal Philosophy

Oh Boy!
