A guy walked into the office wearing a horribly loud shirt and tie. "Do you like my new shirt?" he asked a colleague. "It's made of the finest silk and has got loads of cactuses all over it." "Cacti," said the colleague, correcting him. "Never mind the tie! Look at my shirt!" I think that when you get dressed in the morning, sometimes you're really making a decision about your behaviour for the day. Like if you put on flipflops you're saying, 'Hope I don't get chased today.' Demetri Martin
