It`s like a death throw hard-on 2 minuites too late

The story:

I was teaching English in Slovakia and I used this song in one of my lessons because someone had asked me what irony was. I wrote out the lyrics and we went through them and deceided whether each situation was ironic or just bad luck. I explained the death throw hard-on line like this -" Alanis was in bed with her boyfriend and he couldn`t get it up. She got dressed and was just leaving to get her bus, when he suddenly got the kind of hard-on that a strangled man in his last throws of death gets. And it was too late!" I might have even mentioned Michael Hutchinson! It was only about a month later when I read the lyric motes on the cd cover that I realised there were 20 slovak teenagers who had completely the wrong impression of poor old Alanis. Well she deserves it, she doesn`t know what irony is!
