Here's a bunch of Jackson's -- but he has a few new ones too besides these.
Some of his more "complex" tricks:
limping (walking on three legs)
play dead (bang bang)
hop on my back
run backwards circles around my legs
turn and reverse (he is about 5-6 feet away from me, turns around and reverses or backs up under my legs)
get a tissue when I say 'ah-choo!'
pick his toys up and put them away in a box
hop on my back
covering his eyes
say your prayers
"cop cop" (his feet on mine, and we walk)
skateboarding (still a work in progress)
