Firstly the others are right: even smart guys write & speak "wrong" English :)

Secondly don't forget this is spoken - emphasis and so forth change in the spoken language. I haven't heard it myself (anyone got a link to a recording?) but it could well be dependant on how it was spoken :)

And finally I think applying strict grammar words to what someone has to say does them a lot of injustice :) people just dont work like that do they. Essentially it is saying were going to ignore any meaning or connotation or mistake and take everything literally - god forbid that becomes a fad! :)
