Whats the most used excuse ever?

I was wondering what the most used excuse was in the World, I am thinking that it is probably ” everyone else is doing it” but I am not sure and I think this up for debate because maybe it is just the excuse I have heard all my life from all the lame people I have known over my time here on this planet.

So please chime in when you think you have come up with what you think is the most used excuse in the World and why you think it is.
