Foul Fan Fa Fa

Bertram is really, really into fans. It probably helps that we have a ceiling fan, and five table fans rocking in an effort to stay cool in our apartment this summer. The thing is, he can't say the word fan yet. He points at the spinning wonder and says, "foul." Of course, Hal and I find this funny. We try to break down the word for him with no success, as in the following example:

Parental Units: Fa-ann.
Bert: Fa. Fa. Fa-owl.
Parental Units: Fa-ann. Ann. Nah. Nah.
Bert: Fa. Fa-owl.

We'll be out at a restaurant, and the first thing Bert will notice is the ceiling fan. So he starts pointing and says with great enthusiasm, "foul! foul! foul!"
