Ferrell's character was named Deangelo Vickers.
He first joined the cast in Season 7, Episode 20 ("Training Day"). Michael met Deangelo at a local bar and the two bonded over their shared love of the summer Olympics before realizing that the other one was the person they were supposed to be meeting with.
Kelly Kapoor (Mindy Kaling) attempted to do a "meet cute" with the new boss, which didn't exactly work, and the rest of the office also warmed up to him quickly, prompting jealousy from Michael.
Deangelo revealed that he was passionate about the American Southwest and he did a compelling, ball-free juggling routine for the entire office, making him a quirky and memorable character.
