Over nine seasons, How I Met Your Mother has acquired an impressive list of celebrity guest appearances.
There was Britney Spears as the dippy dermatologist’s assistant obsessed with Ted (Josh Radnor). There was Bryan Cranston as the architect whose buildings always seemed to resemble – how shall we put this delicately? – male anatomy. Even Jane Seymour ditched Dr. Quinn’s period attire for the sexy style of Marshall’s (Jason Segel) cougar law school professor whom Barney (Neil Patrick Harris) just couldn’t tame.
But there’s a much smaller circle of stars who’ve managed to do something even more unique: play themselves. Some became part of long-running gags, others only filmed one-off appearances – but all were legen–wait for it–dary.
Hospitals have emergency doctors. Barney has an emergency tailor. And who else would the New York executive turn to than the Project Runway mentor? This season, Gunn had the esteemed honor of designing Barney’s wedding tux.
In the HIMYM-verse, Philbin is the host of Million Dollar Heads or Tails, a faux game show in which contestants win $1 million if they can correctly guess the outcome of a coin flip. But more important, the former morning show host joined the gang on a season 4 quest to find the best burger in N.Y.C. (and exhibited his Hulk-like strength when the burgers they found weren’t up to snuff).
In Barney’s world, The Karate Kid is actually a tragedy about how Zabka’s Johnny Lawrence has his title stolen from him by a newbie upstart. Knowing this, Robin arranged for the ’80s star to make a surprise appearance at Barney’s bachelor party, earning Zabka a permanent place in Barney’s groom’s party. But if you ask him, Zabka would like to be known as the guy who writes great poetry. (Nice work, Gary Blauman.)
