Laugh out loud, belly laughs, giggles, very very funny, wonderful flashbacks. Could be real!

Dirty grandpa was by far one of the funniest movies I've seen in a long time!! Deniro and Efron were outstanding, Plaza as always gives a perfect and hilarious performance! I would go see this movie several more times!!

Hilarious!!

I thought it was hilarious, but heard other people around me say "That was stupid and disgusting" after the movie was over.
