So Enrique Iglesias and Mandy Moore will guest start on the third season premiere of ‘How I Met Your Mother’ on Monday, 24 September on CBS. Will there be a duet?  We can’t say for sure… Apparently Robin turns up with a new beau, and (big surprise) the kids end up having a night on the town.  I like this show.  It’s funny characters who drink without shame or moral brow-beating. Fine by me.
