At the Philadelphia Museum of Art, famous in movie history as the plaxe where down-and-out boxer Rocky Balboa made his run up all those steps, Megan noticed Jason Segel walking by.

After a chat, the actor, in town shooting a television series, wanted to play a part, as FOX 29 Philadelphia reported.

“Keep doing what you’re doing and I’ll just jump in!” Segel told them.
