I've got to ask. What the hell made you try/think of carrying out this practice? I will try this out of curiosity. But I will make sure no one else is in the surrounding area just in case they get me locked up in a perverts institution.

And just for a laugh.
As Milan is coffee orientated, we should all carry this out in one of their coffee shops.
That will stump them. Conisuers my ass!!
