Quote from Gloria in Open House of Horrors
Manny: Nothing on purpose. It was between periods, right before this big test. I was clearing my mind by practicing some of my Gene Kelly dance moves. Jay: As one does. Manny: Right. And my umbrella accidentally snagged the fire alarm. The principal thought I did it on purpose so we'd miss the test. Gloria: But you didn't! That's it! I'm going to his house!
