I think that that is, hands down, the best phrase out there. I use it every chance I get. Like, say, I walk into a midget on the streets, inadvertently knocking him into my homo roommate thus getting them both run over by a Mack truck. In that case, I think shouting "Holy crap!" would be more than appropriate. Or if, say, I see Richard Simmons raping Gary Coleman one foggy Saturday morning, then once again I strongly feel that "Holy crap!" is a suitable expression. There's just something magical about the notion of feces being holy that gets to me, ya know? It touches me in places I don't normally like to be touched, figuratively speaking of course.
