Shreddies

Saw an ad inside a cab recently for something called 'Shreddies' which are pants (i.e. knickers) both male and female. These apparently are used by people with 'flatulence problems' - presumably who fart a lot. Seems they have charcoal and some other kind of linings which neutralise the pong. Very useful. You wouldn't want to receive some for a Christmas present though. Extraordinary. If you know someone with such a need, go to myshreddies.com.
