My favourite saying in the whole universe. Use it often, and use it anywhere, any time. It's so amazingly versatile! Also try using this phrase, "little baby jesus!". It's a kinder gentler version of "jesus christ!", which I've never been very fond of. I have to admit though, it's much trickier to fit "little baby jesus" into a sentence. It also creates intrigue, either that or confuses people thoroughly. Embrace the chaos your simple words can create.
