I don't know if this was just me, but I am pretty sure that I saw two different episode of one episode. There is this episode where Mat pretends to be sick. Well after his mom leaves the room, they show him take a penny out of his mouth, that he used to heat the thermometer. Then with the same episode I saw it was different, his mom walked out of the room and he heating the thermometer with a flashlight.

I know I saw this, and heard this.
