LPT: If your toddler won't leave you alone, hand them a random object (piece of paper, plastic spoon, hanger,etc) then pretend you need it back.

Most will shout "NO!!" and run to the other end of the room. Then you can sit your ass on the couch. Periodically yell "[Kid]! Give that back, now!" and act like you're going to get up and take it.
