Nothing. Or you can jump. See how ironic that is - the irony is either way something's going to happen.
Irony is defined as:
The expression of one's meaning by using language that normally signifies the opposite, typically for humorous or emphatic effect.
So are parts of the song there for the emphasis (coming up with the most ridiculous yet possible situations) or for a bit of humour?
(Now I feel like a critic). And as for 'shit happens', it was not meant literally. In the context of being ironic more so.
I think they're old links though, from around 2006. A lot of the newer uploads tend to be in a folder.
