There was this guy Ziad, who, for as long as we could remember, had a moustache. In fact, we couldn't even imagine Ziad without a moustache. It's like imagining Anol da without one.
One day, some of the trouble-makers in our class got an electric razor, and we were experimenting with it. I got my sideburns shaved, someone got their eyebrows trimmed. But basically, come lunch time, and we had only one person in mind - Ziad.
So we convinced him, took him into the toilet, and shaved off his moustache. Totally. And there was Ziad clean shaven in front of us!
We took him out in the courtyard, and every single person present had the same expression - eyes staring, mouths open, some giggling, some laughing, while we serenaded him around.
As then came to coup de grace. Our Math teacher (who was also our class teacher) saw us, and, with the same shocked, staring, gaping mouth expression, said, "Ziad.. when I saw you in the morning, I remember very clearly you had a moustache.. where did it go??"
