Store Clerk: Enough! You're it! And no touch backs, no do overs, no erasies, and this whole store is home free!
Harry: Lloyd, can he do that?
Lloyd: Oh yeah Harry. He can. He did. And now...it's on like Donkey Kong. Pay the man.
Harry: Pay the man.
This happens during the scene when Harry and Lloyd offer the little boy 5 dollars to get them slushies. This movie is set in the 80's but notice the $5 he gives him. It is the newer issued $5 that came out in the 90's.
In the scene where Lloyd is eating dinner with Harry and they're talking about the pie, Lloyd says "I like it alot" which is a phrase used in the first Dumb and Dumber movie.
