For years, Matt Wilson has made it a tradition to prank his son Liam on the last day of school. But this year, he went full rockstar. As Liam stepped off the bus, Wilson and his bandmates from Union Suit Rally were waiting, dressed in black wigs and lip-syncing to “School’s Out” by Alice Cooper.

The bus didn’t pull away immediately. Instead, the driver and students stayed to watch the impromptu concert, while Liam, now finishing eighth grade, bolted inside, clearly used to his dad’s antics but still hilariously embarrassed.

Matt Wilson likes to prank his son Liam every year on the last day of school. This year he got his band mates to help him by dressing up and lip syncing to “Schools Out” by Alice Cooper. Liam got off the bus and immediately ran inside while the bus stayed to watch the show!
