What goes through an opera singer's mind during a freeze

There are times, when you're singing a role in an opera, when you must remain motionless on stage for an extended period of time. This happens quite a lot, actually - the reasons may include the following:

• You just died, and have to lie on the floor like a proper corpse;
• The stage director has ordered a "freeze", which is basically what happened in every episode of the old sit-com "Bewitched" when Samantha would wiggle her nose and time would stop for all mortal beings; or
• One of the other artists has a big aria and you have to take care not to disturb the focus of the audience on that music by, well, moving.

These occasions can last for a couple of minutes or for awkwardly lengthy periods during which your arms ache, your nose itches, drops of sweat trickle into your eyes, and your brain is filled with a myriad of relevant and not-so-much relevant thoughts. These could be typical:

• "I could really go for some waffles right now"
• "Did I lock my car?"
• "OMG - if that little kid in the front row doesn't stop swinging his legs back and forth he's gonna turn up missing during intermission..."
• "The third alto from the left in the front row of the chorus is about to fall out of that dress. Not sure we're ready for a topless villager..."
• "Hmmm... this scene lasts another 7 minutes. I'm going to pee my pants in 3 minutes. Problem."
• "...and X = pi. Yes, if my calculations are correct, time travel is possible."
• "Tired of apprentice programs. Tired of covering roles. I'm giving it six more months and then I'm working at Dad's seed & garden store."
• "My foot is asleep."
• "Let's see now, what's my next line? Wait - what IS my next line???  OH CRAP I HAVE NO IDEA WHAT MY NEXT LINE IS."
• "You know, when you think about it, Colbert says funny things, whereas Stewart says things funny. That's the difference."
• "Johnny Depp as Tonto. Hmmmm."
• "My wig is sliding off my head, v-e-r-y  s-l-o-w-l-y. Well, if it lands of the floor, it lands on the floor."
• "The woodwinds look bored down there in the pit. The 2nd clarinet is putting on weight lately."
• "If I move my hand down there very surreptitiously and scratch, I wonder if anyone would notice?"
• "I'm staring right at the conductor, watching the baton, and I don't see a beat anywhere. Geez, my  6-year-old daughter has better stick technique."
• "Yep - no doubt about it. Waffles sound really good."
