Capuccino con Panna

So I'm in my on call room, sipping some capuccino con panna (with whipped cream).. Anyway, I decide I wanna visit the ladies room; u know coffee has a diuretic effect, so I walk out of my room towards the toilet which is around the corner..

In this 10 second walk, I run into 5 people, all of which look at me and give a very exagerated grin, I smile back and keep moving..

In the lady's room, I look at the mirror, and there was it.. The reason of the suspiciously nice grins!

On my upper lip, a very obvious white mustache, stretching from a corner to the other..

Damn you whipped cream!!! How embarrassing :$
