I'm not sure how many of you are aware of this site Ebaum\'s World , but there is a section of the site that features people's prank phone calls using celebrities' sound samples. I suppose of particular interest here, certainly to me, where the Al Pacino prank calls (scroll down), mainly featuring samples of him as 'Richard Roma' from the brilliant Glengarry Glen Ross. ("Oh what a big man you are! Why don't you give me a packet of gum and I'll show you how to chew it!")
