A Belgian, Hans, meets one of his French friends, Pierre, in the
street, and says:
Hans: "Hi, Pierre! I haven't seen you for a long time! How are you?
And your son, what is he doing now?"
Pierre: "He is studying logic."
Hans: "Logic!?! what is that?"
Pierre: "It is a new, very good school in Paris. Ok, here is an
example: You still have your aquarium, don't you?"
Hans: "Yes!"
Pierre: "So it means you like fishes!"
Hans: "Obviously!"
Pierre: "So it means you like animals."
Hans: "Of course!"
Pierre: "So it means you like the Earth."
Hans: "That's right!"
Pierre: "So it means you like women."
Hans: "Yes!"
Pierre: "So it means you're not homosexual!"
Hans: "What a brilliant demonstration!!! Your son is very clever!"
Very impressed, Hans carries on, and meets another friend:
Hans: "Hi! Have you heard about Pierre's son?"
Other: "No!?! What is he doing?"
Hans: "He is studying Logic; it is very impressive! Look, an example:
do you have an aquarium?
Other: "No!"
Hans: "So you're homosexual!"
