Professor:—“I have to ask your indulgence for a few minutes. I left my manuscript at home, but my little son will bring it at once.”
The little son (entering):—“Mother could not find the manuscript, so she sends you the book from which you copied it.”
The Persistent Creditor
Creditor (who is receiving his money at last):—“There are still ten marks missing, if you please!”
Student:—“I shall deduct those from the amount, for rent, since for the past few months you lived at my lodgings more than I did.”
Watchman or Donkey
Student:—“Herr Nachtwächter (nightwatchman), I wish to ask you something. May I call a Nachtwächter a donkey?”
Nachtwächter:—“Just you take yourself off, before I haul you in.”
Student (goes, but returns after a few steps):—“Now listen; I have another question. May I call a donkey a Nachtwächter?”
Nachtwächter:—“You may, for all I care!”
