During an appearance on Conan O'Brien, Charlie Day commented on Danny DeVito's open-ness to performing almost every depraved act that the writers ask him to do.

No! We can't go out like that. Look, if life pushes you down you gotta push back!

And if some punk ass kid humiliates you, you've got to do the only thing thats left to do!
