Did this actually happen in Gintama or are these fake subs?

This meme right hereIf it's real that's quite the esoteric reference for an anime. Prison Break wasn't even that popular in America. Unless there's a Japanese version of Prison Break where the exact same thing happens in S2.Edit: Apparently Prison Break was popular. I'm now interested in when this particular episode of Gintama aired.Edit edit: the episode aired in 2011, two years after Prison Break ended. http://ift.tt/1KHkwQD
