A man is looking at a soccer game, in this case FEYENOORD - AJAX ;
suddenly Feyenoord scores a goal, and the dog applauds.
After a while Feyenoord scores again ( yes this is not a realistic
joke ) and the dog applauds again.
A man who sees this asks the dog's boss what the dog does when Ajax
scores a goal.
Owner : Well, he turns a backward OR forward summersault.
Neighbour : When forward and when backwards?
Owner : Well, it depends on where I kick him.
