Yesterday was Father's Day, and newly-reunited jam band legends Phish decided that it was more than fitting to celebrate on stage in front of thousands of people.

During "Brother," their opening song at last night's Alpine Valley gig, Phish brought out all of their collective children to sit in a bathtub placed in front of them, referencing the song's main lyric, "Somebody's jumping in the tub with their brother!"

Phish previously pulled this gag during a 1992 tour where all of the band's family, friends and crew jumped in a tub while the song was played.

Phish are currently touring for the first time in five years and play next in Colorado at the Red Rocks Amphitheater on July 30th.
