Meatwad: Meatwad's video game system
The video game system Meatwad "Raked leaves all summer to get" is an Atari 2600. Unfortunately, Master Shake comes along and busts his piece of gaming history with a baseball bat.

Meatwad: Bonus pretzal! Bonus pretzals can be found on the classic video game "Pacman".

Visual Reference: "Dad's Garage"
The words "Dad's Garage," written on the wall by the phone, are a reference to Dad's Garage Theatre Company, an Atlanta theatre/improv troupe where several of the show's performers and creators (including Chris Ward (IV), Tiffany Morgan, and Christian Danley) regularly perform.

None: Title of the episode: " Murphy Murph and the Feng Shui Bunch"
This title corrolates with the early 90's band, Marky Mark and the Funky Bunch. Headed up by now-actor Mark Wahlberg.

: Visual Reference
The video game of Marco and Master Shake fighting can be seen in the background of Hank Murphy's bachelor pad in a later episode entitled "Policy."

Visual Reference: "My backpack's got JETS"
This phrase, written somewhere in this episode as posted above, is from a song called "Fett's Vette" by MC Chris, who does just about everything musical, or rap oriented for Adult Swim, and also voices a hand full of characters, noteably Hesh.
