"What Do You Call...?"

Do you want to hear a joke I made up?

Q: What do you call a flying squirrel with no horizontal velocity?

A: A falling squirrel.

Note that I didn't say, "Do you want to hear a good joke I made up?"* Despite—or perhaps because of its awfulness (and hopeless nerdiness)—this joke has found a certain staying power in our domestic conversation, having now been repeated and cited on multiple occasions by multiple members of the family. Feel free to inflict it on others.

* Its creation was prompted by the sight of a squirrel (of the bushy-tailed non-flying variety) falling straight out of a tree onto the street in front of me, momentarily freaking out in panicked confusion, then scurrying to the safety of the curb.
