A mug which has a fingerprint reader at the top of the handle (where one usually rests their thumb). When the mug detects movement (is lifted etc) it emits a piercing alarm unless it detects a registered thumb print on the reader. Never again will someone in the office be able to steal your favourite mug again.-- Morals, Aug 08 2003 What if I just cut off my co-worker's thumb and tape it to his mug?-- DeathNinja, Aug 08 2003 Inspired by car stereos with removable frontplates, I suggest a mug with no handle, but a little catch to accomodate one, and the electronic wherewithall to only engage the handle-catch if you use the correct (ie your own) handle.-- friendlyfire, Aug 08 2003 Just to spite this paranoid cup-coveter, I'd pour something into the mug and drink it from a straw without lifting it from the table.-- jivetalkinrobot, Aug 08 2003 Or a mug that doesn't open unless the correct thumbprint is used.-- RayfordSteele, Aug 08 2003 I thought this was a custom mug with a big picture of your thumb print on it so you can easily proove its yours. You can also add a mug-shot of yourself for easier identification.-- kbecker, Aug 08 2003 Boom - tish!-- Morals, Aug 09 2003 Good but it would make the mug price go crazy.-- NeoPiter, Jul 05 2004 Why not but a cheap, disgusting and tasteless mug that no-one else would want to use? Horrible, but yours without the thumprint scanner. Jaunty little mottos like'Tea, Coffee or Me?' tend to do the trick.-- wagster, Jul 05 2004 wagster, you rule :P-- NeoPiter, Jul 05 2004 random, halfbakery
