Dear How I Met Your Mother showrunners,
Next time you think bringing Britney back will be a good idea, take another look at the episode titled "Everything Must Go." Not good, you guys. Not good at all. The only reason she wasn't HORRIBLE the last time she was on was because she had very little to say, and was not wholly featured. Last night's episode was, well, honestly, not great anyway, but worse because of her performance.
If you insist on doing the stunt casting, can you stick to actual actors? And, I don't know, take a look at what Will and Grace turned into (a joke) and just cast capable people for the roles like you used to?
