It's Always Sunny In Philadelphia: 10 Cameos You (Probably) Missed
7. Pablo Schreiber
Pablo Schreiber appears as Ricky in Season 6, Episode 13, “A Very Sunny Christmas.” When Mac is telling Charlie about his family's Christmas tradition, he realizes that they were actually just robbing people's houses. This included stealing a toy robot from Ricky, a similarly aged boy in the neighborhood. To make up for it, they try to buy toys for Ricky's children. True to the show, this seemingly kind act spirals way out of control.
Schreiber has acted in many TV series and movies, including Orange is the New Black, Weeds, The Wire, Den of Thieves, and Skyscraper. He also plays Master Chief in the upcoming Halo series.
