Want to confuse your friends? Using Internetcalls.com makes it very simple. On the bottom right hand Internetcalls.com allows you to make a free trial call using the website. In one box you are supposed to enter your number in the other box the number you want to reach. Instead I type in one friends number in one box and the other friends number in the other box. What happens is, the website calls up one friend. When they pick up the phone it rings and calls the other friend up for free. When both numbers are connected together, both friends believe they have been called by the other friend. Also fun is connecting your friend to a Pizza delivery service .
