E! Online reports an upcoming episode of "How I Met Your Mother" was written entirely in rhyme. If you're one of the loyal viewers who has soldiered onto the final season, this might leave you with mixed feelings.

Cobie Smulders told E!, "We just shot an episode where the entire thing is in rhyme. And it was so much fun. It's like every second line is a rhyme."

Smulders didn't say when the limerick-filled episode will hit the airwaves, but "HIMYM" has been toying with its format this year. The Monday, Nov. 11 episode will be a flashback episode and feature the return of Bryan Cranston.

Fans are in for a treat in tonight's (Nov. 4) episode: The mother. Show co-creator, Craig Thomas, tweeted a mini spoiler earlier today.

"How I Met Your Mother" airs Mondays, 8 p.m. EST on CBS.
