I love the idea of "oh yeah, oh yeah, oh yeah!"
HAAH while funny in its way also seems a little bit sick considering the source......... the affair etc... maybe that's just me. I like the fruitcake slogan lol
I'd go for either something a bit subtle and feminine that I'd actually wear, or something more of a t-shirt that I'd probably use as nightclothes! Not a huge t-shirt-with-stuff-on-wearer.
Though of course they'd be good if arranging to meet fellow GMRers!
Picture thing - if a photo was done suitably artified and smaller as on a pocket (without the pocket) or maybe on the sleeve, would that satisfy more tastes??
I like the idea of a couple of different classic slogans as appropriate... say a short one like "*thud* would go well on a shirtsleeve just in small writing - humorous to those in the know. But I don't know if that'd be a bit ambitious on the printing/finance front.
