When did bats join rodentia? And did they tell chiroptera when they left?

In On the Origin of the PCs. Amusingly enough, V of all people makes the same mistake of lumping them in with rodents in the Iron Mage sequence.

"I'm Batman!"

"Batman!"
"And buck teeth."
"Bat..."
"Hang it up, man, you're a rat with a cape and anger issues."

Well played, Brian, well played!
