Most Awkward Things to Do In a Crowded Lift / Elevator

A list of the weirdest, most distracting and utterly pointless things to do in an lift full of people that will cause everyone's short vertical journey to be shrouded in an awkward silence. Nothing too explicit or disturbing and try to be creative!
The Top Ten
1 Meow quietly
2 Serenade a random person
3 When the doors open, walk in to the wall instead
4 Try to have a conversation with the 'doors closing' voice
5 One-Person Harlem Shake
6 Press the button with your nose
7 Proclaim yourself 'Lord of the Elevator'
8 Turn around and say "So you're probably wondering why I gathered you all here today"
9 Bring a sandwich, quote Die Hard; "Yippie Kay-yay Motherf*****" and then eat it ravenously
10 Start crying about something meaningless

How about being nervous in them?
