Explain Bear here. Let me break down this high-level comedy for your single-digit IQ. The Calgary Tower is a massive concrete landmark in Canada. The joke uses extreme hyperbole to mock your mother's promiscuity by suggesting she needs a skyscraper to get off. You probably couldn't even climb that tower, let alone understand this joke without me.
