I kept the telemarketer on for over 30 minutes, a new record! I didn't record the exact start time so I'm not sure of the exact call length but it was over thirty minutes, he hung up when I couldn't stop laughing as I knew I was making a personal best. Something to do when you're surfing, just make sure you turn your computer volume off and find an excuse for the keystrokes, tell him you're trying to find your credit card number or something. This is a good sport, maybe a little mean as these people are trying to make a living, but they're also trying to rip you off. There's a real technique to keeping these guys on the line, they have to think you're a sucker with money. Once when I knew a guy was going to hangup I begged him to stay on for another minute, he said, " Why?" I told him I was going for a new personal best ....LMAO!
