Who broke both legs after falling into the pit beside Ann's house?

Andy Dwyer broke both legs after falling into the pit beside Ann's house.

Before the series begins, Andy falls into the abandoned construction pit while trying to retrieve a discarded toaster. The accident leaves him with both legs in casts and prompts his girlfriend, Ann Perkins, to demand that the town address the hazardous site.

The incident launches the pit storyline in the pilot and helps bring Leslie Knope and Ann together. Leslie responds to Ann's complaint by promising to fill in the pit and create a park, turning Andy's injury into the first major public project of the series.

A common mix-up is assuming Andy fell in during the pilot itself. The fall happened before the show's opening events; viewers learn about it through Ann's account. Another important detail is that Andy was not portrayed as a responsible victim: his later explanation reveals the ridiculous toaster-retrieval motive, fitting the character's immature and impulsive personality.

Andy was played by Chris Pratt, whose performance eventually expanded the character from Ann's irresponsible boyfriend into one of the show's central comic figures.
