Howard welcomed singer Katy Perry to the studio. After telling her he loved her music and asked how her traveling-minister parents reacted to her first single, "I Kissed A Girl." Katy said her parents were at her last few shows and are very supportive. Howard wondered if Katy had ever kissed a girl, and Katy admitted she did – but she's never had lesbian sex. Katy then performed an acoustic version of "I Kissed A Girl."
Afterward, Howard asked Katy how large her breasts were, and the answer surprised everyone: DD! Howard and the gang then began begging for a peek, and Katie obliged, lifting up her shirt to show the crew the more revealing top she had on underneath. Later, everyone had a laugh as HowardTV brought up footage of Artie rocking out to Katy's performance on the in-studio monitors.
