Well, with custard creams, oreos, bourbons and jammie dodgers having being pimped already, can I recommend Happy Faces?
The ultimate biscuit site, Nice Cup of Tea and a Sit Down has a good review of them (as well as plenty of other pimpworthy biscuits). I have fond memories of the Happy Faces biscuits and would like to see 'em large!
(Having the world's smallet kitchen, no freezer, and no digicam, I can't really do any pimping of my own, but I can enjoy everyone else's efforts vicariously).
