Octopi Parts

Overhearing my little ones playing a rough-housing kind of game the other day, one of them said "Ow!  I got hit in the tentacles!"

I asked, knowing full well what the answer was going to be, "What?  Your tentacles?  Where are those?"

He answered by pointing.

I corrected his vocabulary.  I probably should not have done that because

1.  Now he uses the correct word at every possible opportunity.
2.  Sisi got freaked about about the idea of octopi and squids.
