There is a plate stuck in a pot, how do I get it out?

My boyfriend doesn’t really cook, and I thought it would be nice to make some spaghetti for dinner, but the pot that is big enough for the noodles has a plate stuck in it.
I have tried turning the pot over and beating the bottom of it, and I have tried running hot water over it.
It’s stubborn and I can’t get it out. I’m kinda mad, so any help would be nice.
