Well what I reckon is .... that all these smokers are actually training their brains to perform on less oxygen, so that when they are not smoking their brains will be basking in unaccustomed oxygen and performing super-brilliant-well.
And then they will take over the world.
They are the agents of a global and very cunning conspiracy.
Anyways - stupid is in the eye of the beholder - so I'm not even gonna look at 'em. Especially that Patrish - she's probably co-ordinator of the whole shebang. She seems terrifyingly not-stupid to me.
