As the self-proclaimed “America's $1 Funnyman,” Neil Hamburger makes his living by making audiences squirm. A sample joke: “Why did God let John Denver die? Because his records weren't selling anymore.” Quintessentially identified by his unsightly and oversized glasses, half-decent tuxedo and horrid comb over, Hamburger’s anti-humor seizes uncomfortable situations and awkward pauses to deliver avant-garde laughs. Despite the endearing self-deprecation of his presence, this 21st-century Andy Kaufman has been subject to his share of heckling and hostility from audiences. Of course, a man isn't likely to give up his day job so fast when he's got the kind of problems Neil apparently does. “I simply owe too much money,” he says. “You've got to pay off all those debts before they let you stop doing shows. You can't quit or those guys will get ya.” However, life's looking up for Mr. Hamburger. Aside from amassing an impressive discography of comedy and cover song albums, he's been in a few movies (Tenacious D: The Pick of Destiny, for one), a handful of TV shows and a Webcast series of his own called Poolside Chats. Neil also has one more dubious accomplishment that he's quite proud of: “It's a real feather in your cap to say that you've been booed at Madison Square Garden.” Hamburger performs 9 p.m. Saturday at the Southgate House. $8 in advance; $10 at door.
