Billy Unger on Lab Rats (2015)

The new season of the DisneyXD action comedy series Lab Rats got another of its leading men shirtless. The ninth episode of the fourth season finds series star Billy Unger stripped down and dressed like a baby in an attempt to get his character's alter-ego, the destructive Spike, to emerge. When the outfit embarrasses him to the point of bringing out his more destructive side, viewers are still treated to Billy wearing next to nothing, as he shows off his muscles in an effort to show dominance.
