Commentating Penalty

[Precept2]

We have a problem with people in our Home Tourney who think they need to commentate the hand. They say stuff like:

"Q9 looks good."
"Be nice to have QJ."

It irritates the crap out of me, and the host is capable of being swayed. When people want a change, they come to me. Other people are getting annoyed by this.

So what's a reasonable penalty for doing this?

Here are some ideas (some of which are absurd), but it needs to stop.

10 minutes
20 minutes
1 BB
2 BB
Match the Pot
$5 out of pocket
