Meanwhile, Marshall and Ted were reliving a tiny piece of their youth: making the 22-hour drive to Chicago for their favorite pizza. But there was a slight problem -- Marshall brought Lily. This was bad from the get-go since Ted was looking forward to a boys' road trip. Then, it became painfully obvious that Lily was a frequent pee-er. This meant lots of stops along the already long drive. But no problem because Marshall had booked them in a quaint little B&B along the way (for couples) meaning no "drive all night" road trip this time around (much to Ted's chagrin). Ted wasn't too keen on staying at the B&B, so he kidnapped Marshall and the two finished the road trip alone. In the end, Lily got the last laugh, though. Both Marshall and Ted wound up with severe stomach pains courtesy of their favorite pizza place.
