Not sure about the world at large, but in the little corner that I live in, I think its a good idea for 2 reasons:
1) Considering that his education / worldview experience is a fraction of what her’s is, if he’s allowed to talk for a few hours straight, there’s a chance he might say something intelligent.
2) Once married, he won’t be able to voice his opinion on anything (unless santioned by wife and / or shver – shvigger) so let him enjoy it while it lasts 🙂
