Pie A La Mold

Since we having been having mold issues in our basement, and Michael insists on checking "Miss Tammy's mold" every so often, mold is at the tip of his tongue, so when we had pie (actually apple turnovers) Mommy asked him if he wanted ice cream with his pie. I told Michael that the correct way to ask Mommy was to say "Mommy, may I please have pie a la mode?" So Michael's interpretation was "Mommy may I have pie a la mold?" I tried to explain to Michael that there was a difference, but the subleties of the English language are still lost to him.
