On my previous team, even with 8 people, too much yakking made standups too slow, and indeed you had many people bored just waiting. No one thought eliminating standups was a good idea, though.
So one guy pulled out a timer. You've got one minute. After one minute, if it's so worth saying that you'll keep talking through the "bzzt bzzt bzzt bzzt" of the annoying alarm, you go ahead. But now you're getting direct feedback against talking without need.
Of course, I make no claim this would work for any other group, much less any particular group. But it helped that team get standups done faster and more productively.
