RB Practice Guy

RB Practice Guy is the thumbnail image to Greg Arkus’ video on YouTube titled “RB 2024 Practice.” RB Practice Guy himself is a cartoon naked man depicted as running in the thumbnail with a white background. RB Practice Guy has become the subject of many goofs, gaffes, and chortles among the Second Lunch Servery friend group. RB Practice Guy is often put up on display on any one of the friend’s in the friend groups computer system screen while they are in the bathroom. They come back and greeted with a sweet treat! RB Practice Guy is hated by a Squire named Randall.

*Patty walks back into the crassroom after using the bathroom, he sees that quissle has put RB Practice Guy on his computer system.* *Patty starts chortling*
“Patty are you watching TikTok’s or RB Practice Guy?” - Randall
“No, I am not screwing around!” - Patty
