Sounds like Ke$ha would be an even worse addition to the Scooby Doo team than she's been to the music industry. To be honest, though, we find this whole story a little implausible. Not because we don't believe in ghosts — we just refuse to believe any creature living or dead would look at Ke$ha and say, "I need to get in on that." But who are we to judge? Maybe they met at a "Things That Make Annoying Noises" conference. At least it explains that bottle of Valtrex we saw floating toward the men's room today.
