Dude #1: They have been underestimating my power.
Dude #2: What?
Dude #1: They have been underestimating my power for quite some time now.
Dude #2: What are you, a supervillain? Who's been underestimating your power? The justice league?
Dude #1: No, the electric company. They say I owe them eight hundred dollars.
Dude #2: Dude, you and I were having two totally different conversations.
