3. Name that tune.
Dying to know what song that is playing on the car radio? Call 866-411-SONG and hold your phone up to the speakers. Just 15 seconds (and a small fee), and 411 SONG will send you a text message with the song name and artist. (This only works on cell phones with SMS capabilities.)
2. Swear like a sailor to skip directly to a human operator.
When that Interactive Voice Response (IVR) system's making you navigate an endless menu of options, put your potty mouth to good use. Some IVR's are programmed to listen for naughty words and speed you along to human help when they hear them. Adam gave this trick a try and dropping the F bomb did indeed zap him right through to a human. We suggest using this trick when you're not within earshot of your co-workers.
