Many happy returns dude ! I'm not sure if anyone will find this funny (but c'mon, we're a CG forum for pete's sake.) A mate gave me this one, I'll share it with you guys:
I would just like to say happy birthday Tyson, and I think it's awesome that you got a picture of cobra commander kicking a puppy on your birthday thread. That is awesome, I think I'm going to get it as a tattoo actually, right on my chest, so that I can tear open my shirt and smell up the place.
And it's great that you can ride a bike, because then you can start a paper route....
