I wanted to express this scenario:
boy: you look better with glasses on.
girl: they make me feel so uncomfortable.
boy: so you'd rather not wear them?
girl: yes?
boy: let me have a look at them, (takes glasses and snaps them in two)
girl: WTF did you do that for?!
boy: (brings out mirror) how do you look without them now?
...not as funny as I thought it would be
