In an attempt to redeem himself to the fans of Y.O.M. after a flubbed Shirt-off-my-back illusion, G.O.B. makes his family's yacht disappear. This is G.O.B.'s most successful illusion. The yacht indeed disappears. The secret? G.O.B. blew it up and sank it. Ta-da!
G.O.B. mentions that he doesn't have Spring Break plans since he was embarrassed by Phillip Litt on the Girls with Low Self-Esteem videos for showing 1-2 flubs from the yacht illusion. In reality, there were 14 flubs. ("Spring Breakout")
