Answer

"I'm fried" - when a computer circuit overheats and burns out, we say (colloquially), "it's fried".  When we talk about ourselves, it means we are so exhausted or stressed that we cannot mentally function. We are like a burnt-out circuit in a computer.  You can also use this to describe a person on drugs.

"Surprise me" - this basically means, "You decide."  It means you trust the other person to make the decision, and pleasantly surprise you with their good choice.
