Steve Carell’s real-life wife Nancy made appearances as Carol, one of Michael’s love interests between Seasons 2 and 3. Michael kept doing typical Michael things to Carol — proposing on the third date, Photoshopping himself into her family photos — so the two didn’t exactly scream “made for each other,” but it always was fun to giggle between commercials about how those two are, like, totally married in the real world!
Rashida Jones
Unlike Amy Adams, who played Jim’s other not-Pam girlfriend in the first season, Rashida Jones’s Karen was actually allowed to have a personality. And it was kind of an awesome one! Unfortunately for Karen, the cute Call of Duty sessions she shared with Jim when he relocated to the Stamford office weren’t enough to keep them together long beyond the show’s third season. You know, when Pam came back into his life. Poor Karen.
Kevin McHale
In Season 4, Kevin “Wheelchair Kid from Glee” McHale made a before-he-was-famous guest appearance as the pizza boy Michael held hostage over an invalid coupon. And he was not in a wheelchair!
Jack Black and Cloris Leachman
In a special Super Bowl special Office episode during the fifth season, Jack Black and Cloris Leachman, made a heavily-promoted appearance as actors in a soap opera Andy was watching, which had Black playing Leachman’s boy toy. Jessica Alba was also in the production-within-a-production, but the best part by far? Andy sobbing at how beautiful the show was.
Amy Ryan
We certainly couldn’t imagine a woman who could deal with all the crazy that is Michael Scott, but the writers of The Office did us a solid in creating one for us. Amy Ryan started appearing in Season 4 as Holly Flax, the only woman in the world as endearingly out of it as our main man Michael. We think we might just be more invested in seeing this couple get their happy ending than we were for Jim and Pam.
Kathy Bates
Kathy Bates joined the cast as the cold-blooded head of Sabre, the printer company that bought out Dunder Mifflin. Her dynamic with Michael was always good, but we’re mostly glad her arrival also signaled the permanent introduction of her nervous assistant Gabe into the regular cast. His Lady Gaga was one for the record books.
Timothy Olyphant
Deadwood‘s Timothy Olyphant brought some unadulterated hunkiness to Dunder Mifflin as new travelling salesman Danny Cordray — which not only gave Meredith and Kelly something to ogle, but also provided Jim and Pam a plotline for a change (something rare and new for new, post-baby seasons!), since Pam and Danny had gone out on a date years prior.
Ricky Gervais
We knew Gervais’s David Brent of the UK Office would eventually have to have a run-in with his American counterpart. Last Thursday, they finally did, perhaps now that Steve Carell’s days left on The Office are numbered. They may have only had a few moments together, but it was enough to satiate our wildest, trans-continental Office fantasies.
