Old and New Jokes

It
is the year 2032, and a father and his son walk the
streets of lower Manhattan. Approaching the site where
the WTC used to be in the end of the 20th century, the
father sighs and comments, "to think that right
here used to be the Twin Towers…"
The son, not understanding, asks his father "What
are the Twin Towers?" The father smiles and looks
at the son, and explains, "The Twin Towers were
two huge buildings that used to be here until 2001,
when the Arabs destroyed them."
The son looks up to his father, and asks, "And
what are the Arabs?"
