A man goes to see the psychiatrist and says, "Doctor, sometimes I think I'm a teepee. Then, I think I'm a wigwam. Then, I think I'm a teepee. Then, I think I'm a wigwam.
The psychiatrist says, "I see your problem. I believe you're two tents."
teepee = a Native American shelter made of wooden poles and animal skins
wigwam = another form of Native American shelter
What's So Funny?
The punchline "two tents" is pronounced the same as "too tense."
