A man is sitting at a bar when he strikes up a conversation with the guy next to him. They start chatting and the man realizes that the guy next to him is a professional comedian.
The comedian starts telling the man some jokes, and after a few minutes, the man says, "You know, I've always wanted to try my hand at stand-up comedy. Do you think you could give me some tips?"
The comedian agrees and says, "Sure, I'll give you one piece of advice: make sure you have a strong opening joke. Something that will grab the audience's attention right away."
So the man goes home and starts writing some jokes. He spends hours perfecting his opening joke, and finally feels ready to take the stage.
He nervously walks out in front of the audience and says, "So, I was at the bar the other day, and I struck up a conversation with a professional comedian. He gave me some advice for my first time doing stand-up. He told me I needed a strong opening joke. So here it goes…"
The man pauses for a moment, takes a deep breath, and says, "Why couldn't the bicycle stand up by itself? Because it was two-tired!"
The audience erupts in laughter, and the man continues with his set, feeling more confident with each joke he tells.
After the show, the comedian approaches the man and says, "I have to admit, that opening joke was fantastic! You really nailed it."
The man smiles proudly and says, "Thanks! I guess you could say I wheeled it out when it counted."
