Lol, that was great! Especially the glasses and "Now I can only see your coat."
Anyone remember Candid Camera? They put a telephone booth in a staff lounge with a door in the back.
A 'new' employee (actor) sat with them all at coffee then said she had to call home.
When she got into the booth she slipped out the back and her 5 year old daughter, dressed exactly in the same outfit took her place and the actor began shrieking that she was shrinking with, "Help me!" for extra drama.
The staff all ran to the payphone and began screaming when they saw this tiny woman and RAN AWAY.
