The only thing you're good enough for.
The only thing udders are good for.
She did it boys!
Boys will be boys
Enthusiasm Is A Good Thing!
you will always be remembered
Karts aren't the only thing she rides.
She takes the whole thing
Almost as good as the real thing ;P
Bryan and the boys, one thing led to another
The important thing is that she tried.
She got the good goods
She can almost swallow the whole thing
She made the old boys day
That's the only thing you're good at
