Pretty damn decent. Doesn't do it for me tho'
As I say so often, anything based on humour is going to be more subject to personal opinion than, say, a game. Or a movie based around action, or graphics, or style.
I dunno, the whole idea of something making us laugh is totally crazy. I suppose if one of us actually worked out what it is that makes others layugh, we'd be millionnaires. Until then, I'll presume that it's a perversion of the normal expectations that makes myself laugh.
Actually scrap that. I'm just saying something, trying to sound like I know something about something I know nothing about.
Basically, my point is that humour is subjective. This didn't do it for me.
