Students Surprise Their Professor with Signs of Appreciation During a Class

Here's a professor who got an awesome end-of-semester surprise from his students. It was during an online class and he noticed their cameras were turned off. He joked about it, and even thought it was his fault but it wasn't. Finally, one student told everyone to turn their cameras on, and you see them all holding homemade signs of appreciation. Stuff like, "Thanks for a great semester." "Thank you for making a difference every day." "We appreciate you Dr. Brown."
