The speaker asked, "Why you can ride a horse but not a zebra?"
Someone shouted, "Zebra is for crossing."
The whole room of attendees broke into laughter.
The speaker then asked, "Why latex is white but wheel which is made of rubber is black?"
He went on to explain the reasons.
You cannot ride on a zebra because it is not domesticated. Wheels are black because a certain chemical is added to strengthen the wheel which turned it black.
The speaker then jokingly said, "Sounds smart right."
He then shared that he spends 30 minutes every day to watch something new to him.
