Best unexpected cameos... **** spoilers!

Conan O'Brien has a bizarre cameo in an episode of the 7th season of How I Met Your Mother. It's about 1 second long and he doesn't say anything but still manages to be funny.

The film made enough money that a 3rd is coming our way - Looking forward to what Sly can pull together for the next iteration. And while we are at it - can we get another Rambo movie?

* Kareem in Airplane -

I look forward to Expendables 3. They should do an expendables movie every decade with all the action stars from the past decade.

Eleon Musk in Iron Man 2.

Arnold Schwarzenegger in "The Rundown" - That one was so quick if you blinked you missed it. I had to stop the DVR and go back a couple of times.

Chuck Yeager "The Right Stuff" - He was the bartender at Pancho's bar in the movie.

I had no idea that was him 😵

Not really a cameo.

But if you watch the show Psych, and have seen the movie Beerfest.

The guy who plays shaun Spencer in Psych has a quick scene in Beerfest, as the delivery guy who gives the germans the "stolen beer" message from the Americans, and promply gets... (This was right before Psych came out on tv, so not really a cameo as I said)

Tom Cruise in Tropic Thunder

This gets my vote. I didn't even know it was him til someone told me. Excellent, and I wish he did more instead of this "Jack Reacher" crap.

Two notables, not mentioned, Keith Richards & Pirates of the Caribbean, Chuck Norris in Dodgeball.

Has anyone ever said that?

Tom Cruise in Tropic Thunder might count, though that's way longer than just a cameo.

TC's in Tropic Thunder was most certainly the best.

Sean Connery in Robin Hood

How about Neil Patrick harris in the first Harold and Kumar movie.

Yep that totally came out of left field and was totally unexpected but I loved it.

I assume that was sarcasm since i am sure he was revealed in the trailers. Also NPH was a main character of the movie thus he cannot be a cameo. Cameo is generally a one scene character.
