How awesome would it be if Robin Thicke came on the show. He could be a old flame of Robin Sparkles, and he comes to NY to get Robin to run away w/him back to Canada before she marries Barney.
Or instead of being an old flame he could still be in love with her from when she was on Space Teens w/his father Alan, and she never reciprocated, and he's still obsessed w/her and he's there to wedding crash and take Robin away.
Re: I have the perfect HIMYM Robin and Barney episode.
