How do you play tennis in tony hawk 4 for xbox. I know you have to find someone names Bjorn or something. How do you do that and what do you do? thanks

Go on the first level (college i think) and skate over to the tennis area and talk to the guys playing tennis. If you are on multiplayer, just both of you go up to the tennis court and an option t play should appear.

You have to be in the career mode and go to college then as you start the level go down the stairs in front of you and look left you should she a quarter pipe some stairs then another quarter pipe. Go up the stairs and go to the end and there will be a tennis court go to the racket on the ground(near the garbage can) stop and a option should come up to press a button to play("b" i think)
