My favourite prank involves putting a little piece of tape over either the end of an ethernet cable or a phone cable.

For the phone cable put it on the handset connection so that they phone rings and then when your victim picks up the phone he/she answers it, but they can't talk to the person.

Autocorrect is definitely a fun one to play around with. I removed the 'h' from as many words I could think of that start with the letter 'h' because my boss was French and never pronounced his h's
