At college in dorm rooms lots of people have wireless printers. You can print off of anyone's printer and they will never know who printed. Printing naughty things is particularly amusing.
"Hey Josh, your printer is spitting out an image of a woman getting boned by a horse!"

"Jesus, I'm a victim of printer hijacking!"

"Haha, gotcha!"
