The big guy in my avatar (RIP) used to send things to the printer from my computer. More complicated because I was at my house about 20 miles away from my work, where the printer was. So I'd have to email someone and say - you know that email conversation we were having? Well Bailey just sent it to the printer. Could you run over there and pick it up? He would also send emails just as I opened them, so the recipient got a blank email.
Love all these stories. Cats are just so entertaining!
