Once upon a time, bar mitzvahs, like the typical Irish communion, were quite sober affairs. Now however it's all about parties with bouncy castles, DJs, presents, the works. Sam Horowitz just took all of them to the next level by basically throwing a concert starring him á la MTV's Super Sweet 16. It's one of the grandest displays of self-worship we've ever seen, and it is glorious. Who wouldn't want backing dancers and their name in 20ft lights? Shame about the song choice though (but we Sam does just wanna dance, love, and dance again).
