Oh Where, Oh Where Has My Fridge Light Bulb Gone?

Kirby and Sam are conspiring against me. While I was dusting in the living room the other day, I heard Kirby in the kitchen say to Sam, "Look at this, Samface!" The fridge opened and closed and they were both laughing. Then Kirby ran off to the bathroom with Sam following. I didn't really think much about it until I went back to the kitchen to finish my cleaning there. Kirby ran in to watch me and when I opened the fridge he and Sam started laughing again. The fridge was dark. I bent down to see if the bulbs had burned out but they were no where to be found! I asked Kirby about it and he said he threw one in the bathroom trash (which I found) and one in the "big trash in the pantry" (which I did not find.) Who knew Kirby could unscrew a light bulb? Where do kids come up with these things??
