Well, I don't exactly remember everything about certain parts of games but there are things in some games that i loved. (These are some of my favorite games but not in this order.)
Super Mario Brothers 3
When you beat the game and it says something like "Sorry Mario the Princess is in another castle. Just kidding. HAHA" I thought that was hysterical, and i couldnt stop laughing.
Legend of Zelda: Link's Awakening DX
I really liked that you could steal from the store, but i really liked how your name changed to THEIF after you stole something. I thought that was funny.
Donkey Kong Country
I liked the way that in the middle of final boss fight King K. Rool goes down and the fake credits start rolling. I remember when i was 7 and i was playing this game with my friend, we had actually thought we beat it. We had gotten all happy, then we saw him get get up and we both were like

.
I think that i remember most of the funny things in the games that i play.
That's all i feel like typing for now, i might edit this later.
