"How I Met Your Mother" is about to get all nursery rhyme on us. Earlier this week, Cobie Smulders let it spill that an upcoming episode of "HIMYM" was written entirely in rhyme and now we have further confirmation.
CBS released a preview of the episode, "Bedtime Stories," which gives a little more backstory to the episode's premise -- baby Marvin can only fall asleep while listening to rhyming bedtime stories -- and some pretty amazing children's book illustrations of the gang. Watch the preview in the clip above.
The rhyming episode of "How I Met Your Mother" will air Monday, Nov. 25 at 8 p.m. EST on CBS.
