Been looking for the answer to #4 since the question was posted, and the only verifiable information I have that Bob Dole has ever even been in a bathroom is from his review of urinal cakes. For the record (as a tribute to Bob Dole) Chief Wiggum doesn't like blue urinal cakes either...
The search function is painful... All these questions are from before my time. I guess I'm just happy on on the board at the Lurker 500.
Thanks to GoBo for the rep and $10 in casino bucks
