I have two:
" When I was 16, my father was so ignorant I could hardly stand to have the old man around. But by the time I turned 21 I was impressed with how much the old man learned in five years" Mark Twain. (Quote may not be exact )
" There is not such thing as bad beer, some just taste better than others and if it is free beer, there is no better tasting." My Dad
And a third because I can not count
"Sex is like pizza, when it is good it is really good and when it is bad......it's still pretty good!" That was from some comedian I saw on an HBO special back in the 80's. Ironically I was watching it with my girlfriend at the time and we were eating pizza and having a few beers. I think that line helped turn my pretty good night into a really good night. I think the comedians name was The Amazing Jonathan.
