The first two seasons of Perfect Strangers hit DVD Feb. 5, and while my upcoming review in EW will say that they’re not worth buying — much of the slapstick is stale, like when Cousin Larry (Mark Linn-Baker) struggles to open a bag of potato chips in the opening moments of the pilot — you do need to see this Fresh Young Balki B (Bronson Pinchot) music video. And tell me what it’s from. And why it’s not on the DVD.
