The Pool Hall scene. Once Jake wakes up he really puts on a show. Sending the cue-ball all over the table so Liz's opponent can't take his shot. Then making sure every single one of the balls lands in a pocket, while she's blind folded.
When Jake levitates Frank and their motorcycle across the army barricade to escape pursuit. ET eat your heart out.
When Jake uses his powers to get an old plane off the ground so he and Frank can catch the escaping villians. It's pretty awesome watching that beat-up ole plane come back to life.
Jake's fine display of aerial acrobatics while he and Frank are chasing Mr. Olympus's helicopter.
