Math Facts Make Me Laugh

Izzy was working independently reviewing some (addition) story problems.  I overheard her reading one particular problem out loud to Maddie.  It went like this:

Chip collected 16 acorns and Dale collected 26 acorns.  How many acorns were added to their stores?

Izzy follows up by saying, what cute names for chipmunks!

Maddie suggests Izzy name her stuffed animals Chip and Dale.

I start laughing, but keep my mouth shut despite the stares from my two innocent daughters.  Chip and Dales for characters in a math problem?  Hmmm.

Apparently mathematicians have a sense of humor. Or not?
