Another idea might be to POS tag the words and only present verb noun combinations, but you'd have to play around a bit to see which parts of speech rendered the best domains.
Anyway, here are some nice sounding domains I've found with this tool:
historicalreading.com
brokencurrency.com
bagelmoon.com
sofacake.com
dancebrick.com
wholesalerreport.com
slimyslime.com (if you're a slime retailer, this is a perfect domain!)
and some not-so-good ones:
tramprugby.com (I would pay to see this)
aftershavejustice.com
beanslime.com
depressedtuesday.com (can we make this a national holiday?)
