Stuff like when Tom called me and asked if he could have a truckload of pork bellies (CME ticker:GBP. And: I told him no.) delivered to our house.
Sadly frozen pork belly futures don't trade anymore and haven't for about 4 years (almost to the day), and the Globex contract was GPB not GBP. But whatever, that sounds like a cool story and you should tell the rest of it :)
