See earlier jokes - he's arrived by now. He got 3/4 of the way there the 2nd time he sang it.
if the distance between 'where he is' and 'there' is decreased by half (50%) with each singing of the song, then unfortunately for BJ he will never actually get there due to how maths works. he will get very close, but there will remain ever so tantalizingly out of reach.
