1.64. A man tries to buy poison to kill his wife. The
pharmacist figures out what he’s up to and finds a way to ensure that he
can’t kill his wife. (CB, from Flitterwochen in der
Hoelle)

1.64 answer: The pharmacist gives the man a cup of coffee to drink while
he’s waiting. After the man has drunk the coffee, the pharmacist says,
“There was poison in that coffee. I’ll give you the antidote if you write a
signed statement that you were planning to kill your wife. I’ll keep the
confession; if anything happens to your wife, I’ll give it to the
police.”
