10 INSANE TV Cameos You've Never Seen
1. John McCain - 24
And finally, a rarest of things now - a rather ironic cameo from a future American presidential candidate in a show that is itself about the attempted assassination of a presidential candidate.
Roughly a year before John McCain announced his presidential campaign - which would ultimately pit him unsuccessfully against Barack Obama - he made an amusingly sly cameo in one of his favourite TV shows, 24.
The hit espionage series, whose Conservative leanings aren't a secret to anyone who's ever seen it, gave Republican McCain a walk-on role in the fifth season's seventh episode.
Almost exactly half-way through said episode, as it returns from a commercial break, McCain can be seen in the top-left corner of the split screen, handing a file to Audrey Raines (Kim Raver) and walking away.
24's famous box-split style - where numerous scenes are often displayed on-screen at once - was basically an ingenious way for the show to sneak McCain's cameo in without most ever noticing.
That the showrunners had him do something so banal just makes it that much more weird.
