I've never been to a Tupperware party, partly because I don't trust a product that specialises in marital aids for sheep, and partly because there are only so many airtight plastic containers a baron and amateur philatelist needs. I like the concept, though: if Tupperware parties were two-chocolates-for-the-price-of-one parties, or bagpipe appliance purchasing parties, or turquoise long john parties, I'd be in like Finn. (Flynn? Pnin? Whoever it was who was in.)
While we're talking communal japes with a consumerist twist, cast your een over this fine proposition, clipped from my local paper:
Headlice removal in your home! Discount for groups of three or more! If this doesn't lead to the rise and rise of Friday evening delousing parties, complete with canapes, then I'll eat my gnat.
