The blond-haired member of the Penguin baseball team was seen in the Prom sequence wearing a suit and tie ensemble. Later when Barney used his telekinetic powers to rip his pants off, revealing his Rolling Stones red bikini briefs, he is now wearing a tuxedo.
When Barney first discovers his ability in the lab, he lifts up a broken piece of glass by looking at it. The black wires used to lift it can be seen clearly when the close-up is occurring. Same thing goes for the dust pan except the wire is clear and it is seen when the wide shot is occurring.
In the close-up of Jane's sweater just before it pops open, you can see that it is buttoned with the left side over the right. When it pops open the buttons stay on the material on the left side of the sweater and there are button holes on the right. The shirt wasn't actually buttoned.
