Here are some pranks to play on a college professor: 
1. Slip a few extra questions onto their test papers that have inappropriate answers. 
2. Put a few extra references in their bibliography without their knowledge.
3. Sneak a few prank balloons into their office.
4. Take an old t-shirt and draw cartoonish caricatures of the professor on it, then hang it in the back of the classroom. 
5. Change the captions of famous art pieces hung in the classroom, so that they make funny references to the professor. 
6. Secretly organise for some of their students to give them a loud, enthusiastic ovation for everything they do and say.
7. Place a few plastic frogs in their office, just to make them jump.
