@seazen true didnt consider that. But even still impressive on the humans part.
I remember years ago at AC there was a thing at one of the casinos where if you could beat a chicken in tic tac toe you won some obscene amount of money. The chicken would peck whichever spot it wanted to pick.
Well what was really goin on was there would be little slides behind each spot that would open revealing food that the chicken would then eat and activate that button. So really it was a computer you played against looking like it was the chicken that made the choices.
Though, still I must say in the case of the other animals it is a bit more impressive as there is a lot of chance involved with picking times and such.
