Everyone's favorite bow tie-wearing prison-dwelling blogger extraordinaire is heading to How I Met Your Mother for the show's final season — but fear not, Mason Treadwell fans. Actor Roger Bart doesn't appear to be leaving ABC's hit drama Revenge any time soon.

According to TV Guide, Roger's been tapped by the CBS sitcom for a guest spot as an employee at the hotel in Farmhamtpon (not to be confused with East Hampton) where Barney and Robin are set to wed. No word yet on how many HIMYM episodes he'll appear in.

Well that's quite a departure from Roger's recurring role on Revenge! Just to jog your memory, last we saw the disgraced writer he was stuck in the slammer for murder of Gordon Murphy, aka the White-Haired Man, after being framed by his arch-nemesis Emily Thorne. Fingers crossed he brings his signature wire-rimmed specs to the HIMYM set!

How I Met Your Mother Season 9 premieres on Monday, Sept. 23 at 8 p.m. ET. Will you tune in? Tell us below.
