Here's a trick guaranteed to fuck with someone's head.
Step 1: Wait for a person to say something--anything at all. (I caught the bus this morning, would you like some tea?)
Step 2: Chuckle (or snicker--your choice) and say 'that sounds like a euphemism for something ...'
Step 3: Wait for their puzzled expression and for them to say 'what?'
Step 4: Chuckle again and say 'think about it ...'
Step 5: Walk away.
