HELPPP!!!!

Use a fork, slide it into the corner and lift

If this wasn't a bot and someone that actually needed help, I'd suggest taking off the pipes from underneath and pushing up with something long. I'm sure whoever it was has solved it by now...

Will it float?

I always have serious suction cups around. I'd suggest putting a little duct tape on the board and then placing a suction cup on that area, and pulling straight up.

Get a friend and put plastic straws against it and suck in. Not gonna work but it will make for a good story!

Impressive

Use a plunger it will suck/ lift the cutting board out of the sink

First you're going to need a lot of gum...

Stab it and pull it up
