Mike Sorrentino, a.k.a Mike "The Situation," is one of the oldest cast of Jersey Shore: Family Vacation. Mike is one of the most recognizable stars from the spin-off series. After debuting on Jersey Shore in 2009, Mike returned along with the rest of the cast. Although the producers initially planned to replace all the cast after the first season, Mike and his co-stars impressed and retained their roles until the final season in 2012. Unsurprisingly, he then returned to the spin-off in 2018 alongside most of the original cast. However, Mike would end up missing most of the third season after he was sentenced to eight months in prison for tax evasion.
