Most TV talk shows are taped before a live studio audience, and all you have to do to become a part of that audience is to request a ticket and then show up at the studio.

But while virtually all sitcoms are taped in Hollywood, only about half of TV's prime talk shows are taped locally. Shows taped here in L.A. include "The Tonight Show" starring Jay Leno (taped at NBC Studios), "On-Air with Ryan Seacrest"" (also taped at Hollywood & Highland), and "The Late Late Show" with Craig Ferguson (taped at CBS TV City.).

But many other popular talk shows are taped in New York - not L.A., including "The Late Show with David Letterman," "Live with Regis & Kelly," "Late Night with Conan O'Brien" and "Saturday Night Live." "Oprah" and "The Jerry Springer Show" are taped in Chicago.

From a fan's perspective, the good thing about being a member of the studio audience at a talk show is that you not only get to see the celebrity host in person (such as Jay Leno), but also their guests - movie stars, TV celebrities, comedians, authors, and statesmen. And as a bonus, many talk shows feature live musical performances from popular singers and groups.

And all of this entertainment and star-gazing won't cost you a penny. The tickets are free for the asking. Following is a guide to the local talk shows which invite the public to join the studio audience:
