Re: BOFH Trainee?
No need to sabotage, just make them 'sugar free with Maltitol' since this is a laxative....
I did get some of those infamous sugar-free gummy bears for Christmas, which helped me avoid significant caloric gains from giant holiday meals. As I hadn't dented the inventory of the 5-pound bag and considered my curiosity satisfied (teh interweb rumors were true!), I was happy to turn the remainder over to my brother.
He's a fire fighter and the popular prank at the station was to put million-Scoville hot sauce on the rims of coffee mugs or toothbrushes. They weren't ready for a bowl of innocuous, tasty gummy bears.
