Scott Pilgrim and Ramona Flowers are from a comic called Scott Pilgrim.
as Scott Pilgrim.
I can totally understand why these two chose the costumes they did. They were hoping to bank on the success the book series has been gaining; the series will be having a movie and beat 'em up game coming out soon to celebrate the release of the final book in the series coming this summer. I'd say they banked on the right money truck. XD They really did a good job with the costume, though I am still perplexed as to why they had to write SP on Scott's shirt at all, since something like that never shows up at all in the series.
