GREY'S ANATOMY / PRIVATE PRACTICE crossover?

greys-private-practice

Good buddy Matt Mittovich over at TVGuide is posting that they’ve learned exclusively that PRIVATE PRACTICE and GREY’S ANATOMY have a big crossover February sweeps planned.

That gets me thinking – does PRIVATE PRACTICE need a good dose of whatever creative juices are flowing over at GREY’S? Will this negatively affect either show?

What are your thoughts on the possibility?
