Looking.......Title......SOLVED!!!!!!!!

A few weeks ago channel surfing and had to get up for something as I was watching this movie. When I came back to sit down the movie was over with so I couldn’t check the title on the TV guide

Anyway, it was a cop or undercover agent who was posing as a schoolteacher I think to some very young kids, I think first grade, right around that age group. It seemed like a comedy for the few moments I saw it.

Anyone
