One of my favorite character actors was the late, great Jimmy Finlayson — the only man to ever steal scenes from Stan Laurel and Oliver Hardy. Among Fin's many comic talents was an amazing capacity for double-takes that sometimes graduated to triple-takes and even quadruple-takes. He was a great "reacter," which made him the perfect foil for Stan and Ollie. Often, when one or both did something stupid or outrageous, he would give out with a loud, painful "D'oh!" His cry lives on in the vocabulary of one Homer Simpson as this article relates. [Warning: Beware of annoying pop-up ad. It's enough to make you go "D'oh!"]
