How funny is fuck?

Doctor Pon's close personal friend, Russell Brand, recently said that Doctor Pon is as funny as fuck.
However, I'm not sure how funny that is, so expect a thorough investigation using this formula:

x-(o/h) = fuck

I can't find many mathematical symbols, so I just used a bit of punctuation instead. Probably makes no difference.

I'm not sure what the letters stand for either.


Note: Doctor Pon is a habitual liar. He has never met Russell Brand, and it is highly unlikely that Russell Brand said the above things (but it is possible).
