The bolt guy is a tradesperson in Springfield. His job involves bolting things down to keep them secure. During Springfield's Do What You Feel Festival, he was supposed to double-bolt down the platform which James Brown would stand on during his performance. However, he decided he "didn't feel like it", and referencing Springfield's trend of listening to whatever your inner desires are, he elected not to do it. This led the platform to fall down with Brown on it, beginning to hint to the people of Springfield that always listening to your desires can have consequences.
