If ABC brings Trish back to tv, they need to put her on a different show. "The Gold-Digging Whore"? The concept could be that she has 25 charming, goodlooking men, but only one of them is rich, see how good her nose for gold is. Or, "Can She Make It 60?"
Seriously, it would just be tacky to have her as the Bachelorette. "Oooh look, I've got 25 guys here all for me! And I can't wait to wrap my pretty, long legs around each one of them." Ick.
