It's very easy to overlook Danny DeVito — and no, that's not a joke about his height. The actor and director, who turns 76 today, has been a staple of the meme community for years, but no one gets that much staying power from just one character, one look or one nice egg in a trying time.

DeVito was a well-known cultural figure starting in the mid-1970s, and he's never left, being able to move with the times for more than a half-century. Everything about him is instantly memorable in a way that will never go out of style, but he wouldn't be the internet staple he is today without his willingness to do anything for a joke on It's Always Sunny In Philadelphia, or his notorious Twitter account. His birthday should be an occasion for celebrating not only the man, but his work.
