While we were on the plane we heard a mother and daughter talking behind us...

Daughter: You know, the Space Needle is only ten feet tall. And they use it to impale people. Impale.
Mother: They call this airport Sea-Tac because it's between Seattle and Tacoma.
Daughter: That's really interesting.
Mother: You know, Dad's first truck was a Tacoma.
Daughter: That's useless information. That information is rejected!
Mother: Your Dad doesn't have that truck any more. Now he has a Tundra.
Daughter: Mom, the tundra is an essential ecosystem.
