It's Always Sunny in Philadelphia season 2
season of television series

The second season of the American television sitcom series It's Always Sunny in Philadelphia premiered on FX on June 29, 2006. The season contains 10 episodes and concluded airing on August 17, 2006.
Production
The series' second season introduces veteran actor Danny DeVito portraying Dennis and Dee's father Frank, who moves in with temporary wheelchair user Charlie following a car accident, and blackmails his way into the group. Before production of the second season began, series creator Rob McElhenney found out that DeVito was a fan of the show and a friend of FX president, John Landgraf. McElhenney asked Landgraf to set up a meeting. McElhenney met DeVito at his home and pitched DeVito's character, Frank Reynolds. DeVito agreed to star in the show, but was only available for twenty days. To have Frank Reynolds in all ten episodes of the second season, all of DeVito's scenes were filmed before filming the remainder of the season.

Why this record matters
The phrase “season of television series” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Reception evidence should be dated and situated: later canonical status may differ sharply from the work’s initial circulation. The source revision retrieved here is dated May 10, 2026. The linked authority identifier is Q3727893. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2006.
Titles can refer to several editions, objects or performances, making precise identification essential before interpretation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
