Hmmm...

Funnier than a rubber crutch
Funnier than a diarrhetic without toilet paper
Funnier than the time Granma fell into the outhouse

More fun that a rubber crutch
More fun than a diarrhetic without toilet paper
More fun than the time Granma fell into the outhouse

Watching that was fun.
That was funnier than the last time.
That was the funniest thing I've ever seen.
Of everything I've seen, that was the funniest.

Oh, never mind.
