Nothing big, but the simple ones are always the best
I've had a few of the new guys at work with this over the years.
When we have a problem with a HP printer I ask them to log a warranty support call. Because they're new they normally don't know the phone number, so I offer to get it off the web for them. I then proceed to get the HP sauce Head Office number. The conversation that follows probably only lasts a couple of minutes, but it's dead funny listerning to our guy trying desparately convince the HP sauce receptionist that it's definately a printer problem. Normally ends with the person at the other end slamming the phone down.
