Gru's minions are the epitome of cool. Sure, they may look like simple minded servants but that's because their small brains don't have the capacity to feel complex emotions. Every cool person in existence suffers from this same deficiancy. John Wayne was famously dumb. Clint Eastwood's best friend is a wooden chair. Being as dumb as rocks is one of the coolest things you can be. So, next time you see a cool person just smile and count your blessings.
