Whoops

So i made muffins a few weekends ago and used a knife to run alongside the edges to pop them out. Then later that morning we were running out the door in a hurry and Mike quickly put the muffins back in the oven so they wouldn't be sitting out on the counter where a curious cat might be. Anyway fast forward to later in the week, i was cooking lasagna in the oven (the muffins have long since been eaten) and kept smelling something funny...like chemicals. Finally i couldn't stand it anymore and took out the pan and found the culprit!

I guess that was an "whoops!"
