at one point, it was nearly a once a day occurrence. funny story though, i was at the grocery's yeserday before studying at the library with friends and i got rick rolled. as soon as i walked in, the song started playing and i stayed just long enough to hear the whole song.
what i love doing though is siting in my friends car and driving up to people with the windows rolled down. we call out to them and play the song. one guy actually goes to us "you got me, i got rick rolled"
