An old lady comes in for her medical check-up:

“Doctor Ribbit, you remember how you warned me that I should avoid going up and down stairs as much as I can?”

“You know, I’m not sure it was such a great idea doctor… I have to say all that climbing up and down the rainwater downpipe is becoming quite hard!”
