Tyra's mocking Oprah these days. My hunch is that although she's outwardly making fun, Tyra's really, truly, cross-her-heart haunted by Oprah's existence. Granted, it's a hard act to follow. Oprah gifts her audiences with $1,000 debit cards to donate to charity; Tyra counters with the gift of Vaseline. Hmm...Nice try, Tyra.
