Engineer Alvin Delloro handles the technical aspects of the show and runs (hangs up on) bad calls, although Rome occasionally runs his own calls with a "live" manual buzzer. He is most famous for Alvin's Mix, for putting together "The Week That Was" every Friday, and putting together Jim's podcast, "The Daily Jungle". At the beginning of his career he had a quick trigger-finger in regards to running calls, occasionally running calls that Rome would have deemed acceptable.

Good old Alvin married on November 15, 2008.

His birthday is June 3, which is coincidentally the same date that 3 Day Weekend made its debut on the show with "Mr. Automatic."

Running jokes about Alvin include his voice making him sound considerably younger than he is, as well as the number of kids that he and his wife have had.
