That's what I like about this story! Pick a stupid idea and just follow it through to it's conclusion for no reason. You'll create all your best stories doing that.
For example - on holiday myself and a friend decided to paddle "as far round the coast as we can" in an inflatable dingy and a crate of beer. We met some naked hermits round the coast, and things just went weirder from there. We still laugh about it 15 years later.
Life is about creating experiences for yourself that you'll remember. Often those experiences aren't going to happen by making sensible choices...
