Ben Stiller -- My Stick is the Longest You've Ever Seen!

Ben Stiller whipped out an extra long surprise at the 'Zoolander 2' premiere -- something totally necessary when your career is being "professionally good looking."

Stiller and the cast pulled off a record breaking selfie Thursday night in London with a 28 foot long selfie stick!

Cast members Owen Wilson, Kristen Wiig, Will Ferrell, Penelope Cruz and Justin Theroux all squeezed into the shot, along with many others -- they had plenty of room ... with a stick THAT big.

Seriously, they look like ants ... that could totally fit in the Center For Kids Who Can't Read Good And Wanna Learn To Do Other Stuff Good Too.
