Man walks into a psychologists office and says "Doc. You gotta help Me! I'm having these terrible dreams!"
Doc asks the guy "what happens in these bad dreams?"
The guy says "Sometimes I'm a teepee, then I'm a wigwam, then a teepee, then a wigwam, teepee, wigwam, teepee, wigwam. It's all night! I can't take it!"
Doc says "you've got to calm down. You're too tense."
