I use that game and I like the way the whole team is involved with the forfeits. It's essential with games where kids take a turn to minimise hanging around in between turns, after all one go every 24 is not many!
To save time and keep the game moving fast kids doing a forfeit or dance don't have to come to the front but can stand and do it at the desk or in a space next to the desk.
There are lots of great ideas on this site but for those who want a book to carry around to class here's a really good one:

You can get it on Amazon France, Germany, Italy, Spain and the US too.
