The marketing aspect is definitely a positive, but I'd fear it may make adoption of your services in the corporate world a little difficult.
On the flip side, we actually had one VC who turned us away because he hated our new name... but Fukime him.
The larger problem I see with your name is that people won't know how to pronounce it/spell it. Buy all the alternates and redirect them, but also take this feedback into account - you might find it worthwhile to change your name.
I think the overall marketability of a humorous/cool/different name is great, as long as it isn't in the realm of possibly being distasteful to a large number of people.
I think many may discredit the company immediately, thinking it is a joke or satire.
