The boys very first on camera example of telekinetics is them throwing a baseball at each others faces. Until Andrew finally shows us how its done the footage wouldn't have been out of place in an episode of Jackass
The guys' various acts of telekinetic abuse at the mall.
Steve: (after moving a woman's car) Yes, it was the black guy this time. Telekinetically animated teddy bear: (to surprised little kid) What'chu lookin' at girl?! Stay in school!
During the first flying scene: "Hey, what's that noise?"
Before that: "Engage hyperspeed!" "WHERE THE HELL ARE WE?"
While Steve is glomping Andrew for saving him, Matt randomly falls out of the sky and rolls to a stop nearby.
"HE'S A NINJA!"
During the rave early in the film, Matt attempts to get philosophical to attract Casey's attention. Andrew's response:
"Hey, Matt? What did Jung say about glowsticks?"
The first two times Matt tries to fly, he leaps into the air...and lands flat on his face. The second time, he backflips himself into the ground.
And then Andrew gets it on his first go, and Matt tries again... And fails once again, much to the floating Steven & Andrew's amusement.
