I have received tons of gags over the years and have compiled them into small booklets called variously "Richard's little book of gags  (RLBOG)". Enjoy.

Besides the stuff above here's a few vids I thought merit inclusion

Fart (656k)   Duh, I wonder what happens if I light my own fart?

Shock (523k)     Duh, I wonder what happens if I grab this live wire?

Aligator (307k)  Duh, I wonder what happens if I put my head in an aligator's mouth?

Things1 (637k) 3 things to do while the boss is out of the office.

Things2 (741k)  

Things3 (321k)
