He matured and was in college, when you're entering into adulthood, it really looks stupid when a 18/19 yr old acting like a 12/13 yr old. Gotta growup at some point. Plus he looked better with the low cut fro.
What I didn't like was those old man sweaters they had Ralph in. What was with those sweaters with patches on the elbows and zipped up to his neck?
