91 Pin Strike in Power Bowling Training
To get an automatic 91 pin strike in the last round of Power Bowling, Throw the ball on the right or left rail (depending on if you are right or left handed) so that it stays on it the whole time.

Glitch: Knock down other players pins in bowling
This is best done on 2 player mode but I hear its possible by yourself. In bowling, if you aim your arrow to the very end of the lane, then move your character to the end aswell, you can throw the ball onto the other players lane, most likly it will go in their gutter, but if your talented enough, you can get it to knock down their pins. This even coiunts on your score!
Pitch Underhand
While pitching, press [2] before throwing. To return to normal pitching press [1].
Getting pro in either tennis or boxing
If you get pro, which is over 1000 points, then in either sport, the reward is a bigger audience, and all of your Miis that aren't being played get put into the audience. If you make a bunch of random Miis, they will all be there.

To make the crowd laugh in bowling, move to either of the gutters in your lane, turn into opposite lane, and bowl so the ball goes over the barier between the lanes. The ball will go into the gutter in the opposite lane and the crowd will laugh.
Easter Egg: Scare Crowd in Bowling
To scare the crowd while bowling, start the regular motion for bowling and let go on the backswing. The ball will fly backwards and the crowd will scream and jump.
