The boss, Frank, from Mad World. I remember going to the GameFaq forum and everybody complained about the boss being "too cheap" or hard. Frank was and is pretty easy and boring to fight. A bit tedious, but nowhere near hard as people made him out to be. Apparently, a lot of players died on their first playthrough because of him. I only got killed by him one time, and that was on my third playthrough on Hard.
Sonic 1's Labyrinth Zone. If I can get through this stage easily at the age of 4, what's everyone else's excuse? People still have trouble with this stage now.
