Here's one: The usual setup with photo day. CT is about to chew him out when the Principal walks up "Oh Jim Teacher! No suit?" "No one told me" and principal is all "Hmm...what can we do?" Have a blank transitory frame or maybe one of the CT with no caption. The final frame has all the teachers with the principal and Jim Teacher looking really happy and with big smiles standing next to each other, while CT is in the corner of the group with a huge scowl.
