"And One to Grow On" is the eleventh episode of the fifth season of the American sitcom Modern Family, and the series' 107th overall. It was aired on January 8, 2014. The episode was written by Jeffrey Richman and directed by Gail Mancuso.

Phil (Ty Burrell) tricks Luke (Nolan Gould) into taking some ballroom dance lessons by lying to him that they will go to an "autopsy camp". Luke is very unhappy after his first lesson and is angry at Phil. On their way back home, they are pulled over by an officer for what seems to be just a license and registration check. However, Phil ends up in jail thanks to a pile of unpaid parking tickets from Haley (Sarah Hyland). Phil calls Claire (Julie Bowen) to ask her to come and bail him out, but Claire can not remember Phil's complex mnemonic codes of where the money is. She searches all over the house and when she finally finds it after a couple of hours, she heads to the jail to bail Phil out.

In the meantime, Alex's (Ariel Winter) test for her driving license is soon and because Claire can not stand being with Alex in the car while she is driving, she is secretly paying Haley to drive with her for her lessons. Alex does not know about it until Claire calls Haley to tell her that her father is in jail because of her unpaid parking tickets. Alex starts giving her a lesson about how to park and Haley, to make her stop, tells her that their mom pays her to drive with her.

Meanwhile, Mitch (Jesse Tyler Ferguson) and Cam (Eric Stonestreet) continue their wedding plans and try to find a venue for the upcoming event. They find the perfect place that Cam always wanted, but Mitch is hesitant to book it due to the cost. In the few minutes they take to decide, the place is booked for the date they wanted by one of Cam's students for her Sweet 16 party.

Mitch and Cam are not willing to pick another date so Cam comes up with a plan. He knows that his student was going to have the party with her best friend someplace else, but the two girls Tracy (Alisha Boe) and Sophie (Ariela Barer) get into a fight; his plan is to make them up so they will have the party together as they originally planned and give up the location he and Mitch want. Both of them manage to get the two girls back together, but the final result is not what they hoped.
