OK - why did it take me until today to find out the Macy's Thanksgiving Day parade got rickrolled? Even the Telegraph covered it. I obviously need to expand my reading list again!
I saw this, we always watch the parade and I walked out and saw him singing and said "oh my god, they just got rickrolled!" The funniest thing as that my sisters had never heard of it and doubted it until the announcer said it on TV. What a riot!
