The stand up should be capped to about 15 minutes, so there almost shouldn't be enough time for anyone to realize its boring. However, you could try planking instead of standing, choose a cheesy theme song to let everyone know its time to start (think "You're the Best" by Joe Esposito). Maybe play hacky sack while your standing up and choose the order of who goes next by passing it around the group. Take a stand up walk, or hold it in a different place around the office so you get to see teams you wouldn't ordinarily interact with. The best way to make it work is probably to try and get the team to inject some of their own interests and personalities into it. Find out what they think is fun and get creative with trying to theme it.
