"Winning an argument is like winning the special olympics, you're still a retard." My brother told me this after I beat him in a name calling contest.

Politically incorrect of course but the original has to do with arguing on the internet:

I agree, certainly not the most politically correct -- sort of reminds me of a quote by Thomas Paine though: "To argue with a man who has renounced the use and authority of reason, and whose philosophy consists in holding humanity in contempt, is like administering medicine to the dead, or endeavoring to convert an atheist by scripture."

I think it is funny! Lol
