use the controller a bit harder than usuall, hope it helps!

aim your wii stick at the tv and swipe it hard!!!

No one seems to know, it happens randomly which makes you think other "random" mistakes are not skill related either!

dont move your hand. just move your wrist

All u have 2 do is wait till the ball gets to the top and hit it it might take some practice though

get a lot of skill points and it will happen vary oftin

if your a pro it will happen 75% of the time

Really fling your arm at it

Might not work but, Oh well , it would be worth a shot.

i fink u shud jst blast it as hard az u posibly cn n hope it woks

or

b cum a pro

just hit harder

hit the very end of the tennis racket...
OR HOLD B!!!

just flick your hand while pressing B it works about 50.5% of the time
