When you think about it this song seems to be about doctor who and tardis relationship: My hearts a tart, your body's rent (the doctor's heart is like on sale because he constantly loses companions and then gets new ones; the body of the tardis is rent because the doctor's companions come and go very quickly) Sucker love, a box I choose No other box I choose to use (this is about the tardis) Every me and every you (this is about the different tardises and doctors because the tardis regenerates along with every doctor) Someone to bruise and leaves behind (this is about the companions) All alone in space and time (about the doctor himself because he is the last of his kind and travels through space and time) Something borrowed, something blue (this line is clearly about Doctor Who because it was in the show and tells about the tardis) My hearts a tart, your body's rent (the doctor's heart is like on sale because he constantly loses companions and then gets new ones; the body of the tardis is rent because the doctor's companions come and go very quickly) I'm a huge doctor who fan and that's why this song is very-very special to me!
