My Sister-In-Law...the Casserole

I walked up to my wife, Shelley, the other night and said, "You won't believe the dream I had last night." She responded with, "Oh yeah! I dreamed that Lesley (my sister-in-law) was a casserole!" Her dream won, clearly, no matter WHAT my dream was! I got the details of this living casserole and the drawing is below. She said that one moment it was Lesley, and the next, it was a 2-sided casserole with googly eyes and wheels turned up on it's sides. It wasn't sentient. Shelley had no problem with her sister being a casserole on wheels, but she was distressed that someone had eaten part of it! Weird dreams are the best!
