I was interested in learning French after seeing this joke:
3 dogs are competing in a swimming race. There is an English dog named "one two three"; a German dog named "eins zwei drei"; and a French dog named "un deux trois". The dogs all swim across a lake. The English dog finishes first. The German dog finishes second. But the French dog is nowhere to be found.
Because un deux trois quartre cinq.
But it wasn't a joke when I learned that to count to 97, you say 4 * 20 + 10 + 7. I had a 6ure and 5 to my knees and pray God to 7 the French language on fire ... I had e9.
