Jack Smitty
A human sponge who soaks up other people's energy and then tries to pass it off as his own.
He took my idea for the project and said it was his. I called him a sponge stealer.
He copied my joke and said he made it up. I told him he was a joke thief.
He wore my shirt and said it was his favorite. I told him he was a fashion sponge.
