Jimmy Kimmel has crossed over to the world of The Simpsons.
On Thursday night's Jimmy Kimmel Live! the late-night host visits the Simpson house in Springfield, where he meets Homer and Maggie.
"If you drop her, she'll get you back," Homer ominously warns Kimmel as he takes the baby in his arms.
When Kimmel asks how old Maggie is, Homer replies: "I never ask a lady her age."
Says Kimmel, referencing that the Simpsons characters never age: "Yeah, but she's been a baby for a while. Have you ever cleaned this pacifier?"
Replies an indignant Homer: "Hey, don't judge me just 'cause I never washed a pacifier or know how old my daughter is."
The full bit airs Thursday night on Jimmy Kimmel Live! (11:35 p.m. on ABC), three days ahead of The Simpsons' 600th episode (8 p.m. Sunday on Fox).
The episode, which is the show's annual Halloween special, dubbed "Treehouse of Horror XXVII," also will mark the show's first episode to feature a virtual reality experience, with the couch gag in the opening credits available to view in VR using the Google Spotlight Stories app via iOS and Android and any Google Cardboard viewer.
