On a special Cinco de Mayo episode, Jerry explores his Mexican ancestry with a live broadcast from Teotihuacan. Or maybe he just plays 4 new tunes from tkjingles.com (including "Obenshain"), a few great oldies, and 3 new bonus parodies of R.E.M., the Ronettes, and Weezer. Featuring jingles by Dgaerlan, Hampton Nager, Kj Ohnstad, John Peter, Patrick Moffett, Byron Cotter, Joe Aro, and Jerry Negrelli! All that, plus iTunes reviews, e-mail and tweets in the mailbag!
