When Ugly Betty moves to Wednesday nights in January, viewers will have an especially hilarious reason to tune in:

Modern Family star Jesse Tyler Ferguson has agreed to reprise his season one role as Dr. Farkus, Betty's orthodontist, on the show's first installment of 2010, which will air on January 6.

Might Ferguson, who plays Mitchell on the funniest new show of the season, perform the history braces removal on Betty?

Executive producer Silvio Horta remained mum on that topic when asked by Michael Ausiello. He simply said:

“It’s a really fun scene between the two of them."

Fortunately, ABC viewers won't even need to turn the channel that night to find out. Modern Family airs at 9, while Ugly Betty slides into the 10 p.m. time slot for the remainder of its season.
