What’s the funniest/best thing you can think of to have written on a work coffee mug? E.g. “If you’re reading this .. etc etc etc”?

my physical therapist, sits at a table with mostly older people. Sometimes it seems to be a bore. Was thinking of a coffee mug that can involve everyone & really lift the mood, with writing that could bring laughter to the table . For example “If you’re reading this, tell us the funniest thing you remember from the past week”. “Lets make this fun. Randomly blurt out the funniest sound you can make” That’s not good enough though I know there must be more that can be perfect
