These CUTE signs can be printed and laminated to use with the popular teacher "pranks" you see on Pinterest. It's an editable PowerPoint file, so you you can change the details as needed.
The November prank is "You've been Gobbled." Leave an autumn-themed treat by a fellow teacher's door and post this sign with it.
The December prank is "You've been Snowballed." Find a stuffed or inflatable snowman to leave (secretly) in another teacher's room and post this sign above it. Inflatable yard decorations work great for this!
