[The challenge reminded me of the old joke:
A man was at the bar, drinking, when another, obviously very tired, man, came in.
"You're looking a bit washed out, old chap; what have you been doing?"
"My chores"
"What chores?"
"Thanks, I'll have a pint of bitter".
The next day the same man was at the bar when a man, looking like the one from the previous day, came in.
"Aren't you the chap who conned me out of a pint yesterday?"
"No, I've never been in this pub before"
"You must have a double"
"Thanks, make it a Scotch"]
