Busy Philipps had quite the surprise up her sleeve when she invited Jenna Fischer onto her late-night show, Busy Tonight, on Tuesday. The host presented Jenna with a series of mysterious boxes containing early birthday gifts from her former The Office costars [1], including a banjo from Ed Helms and a container of Trader Joe's raisin crisps from Ellie Kemper. Last but certainly not least, Jenna — who turns 45 on March 7 — opened an enormous cardboard box, and much to her surprise, out popped Michael Scott [2] — er, Steve Carell [3]! Unfortunately, no "that's what she said" jokes were exchanged, but Jenna's reaction was still pretty darn hysterical. This one just might rival all those glorious pranks Jim Halpert pulls on Dwight Schrute [4].
