Which Doobie U B? is the debut studio album from 1993 by the Latino rap group Funkdoobiest, who werean American rap group from Los Angeles, California. The original members were Son Doobie, DJ Ralph M and Tomahawk Funk. DJ Muggs was the executive producer for this album. Tracks on the album are performed by Son Doobie and Tomahawk Funk, including additional Cypress Hill member B-Real on the track “Wopbabalubop”.

The album is highly recommended if you’re a fan of Cypress Hill productions. “It all works anyway”, according to Allmusic review writer Steve Huey, he continues “Muggs is in his absolute prime as a producer here, and Son Doobie’s rhymes are fittingly surreal and stoner-friendly, albeit more cartoonish than menacing like his Cypress counterpart”. The album title derived from a line in an episode of the 1970s sitcom What’s Happening!!, when the main character, Raj, is introduced to special guests The Doobie Brothers.

Which Doobie U B? is available on black vinyl.
