Mothman

He didn't quite think the whole moth thing through, did he? This reminds me of an old joke. On a late afternoon in December, a guy walks into a dentist's office. They seat him in the chair, and the dentist comes in. 

 

Dentist: What seems to be the problem? 

 

Man: Ya gotta help me, doc. Sometimes I think I'm a moth. 

 

Dentist: You need to see a psychiatrist. I'm a dentist. Why did you come in here? 

 

Man: The light was on.
