What interesting things can I do to pass time, while on a boring conference call?

I’m stuck in conference call purgatory. I’m being punished for something – I’m just not sure what that is, yet.

I’m trying to pass time while on the call, without getting too distracted. Please jellies, help a bored jelly out. I’m stuck on this call for about one more hour.

I’m only on this call to listen. I don’t have to speak. I really am paying attention to the parts that I must pay attention to; unfortunately, those parts of the call are spread out. Beginning and end of the call.
