Update September 8, 2007:
I have to admit that she dealt with it rather well when I leaped across the kitchen to snatch the egg from her grip before she could begin to break the shell. When everyone had recovered from my surprise leap, largely I suspect in allowance of my somewhat regular odd (nerdly) behaviors, I asked her "how long do you think it would take you to peel this egg?"
"A few minutes," she responded.
I then asked, "what would you say if I told you I could to do it in under 5 seconds?"
"Time me." I used the technique pictured below. It took 3.5 seconds.
10 seconds of stunned silence followed, whereupon she shouted, "That was TOTALLY COOL!"
Ah yes. Nerd pride.
