You bought a pony you thought was multi-talented! Turns out it can only do one trick. What trick would you like it to do for you and why?

Modest request. Tea is not my cuppa tea but I know tea drinkers are very devoted. If you drink a lot of tea then that  trick would certainly come in handy.  But if, like me,  you cannot abide tea it would be ironic! An unused trick which would make the pony completely useless.  So how much tea do you drink each day anyway? Thank you for your reply Plingsby! :)
