Whoa, this marathon analogy is cute!

It's even more hilarious if you go all the way with it...
"I can run a marathon in 3 hours. In fact, I know a whole bunch of people who can do it. We run it every year. It's great."
"That's cool! I happen to have a million dollars to give to anyone who can run a marathon in 3 hours. Would you care for some easy cash?"
"You know, I would, but I'm feeling kinda sick today and I'm not wearing the right shoes. But I ran two weeks ago. Is it enough if I just give you a photo of myself holding the winning certificate?"
"Sorry, you see, the deal is that you must actually run it in front of me. But hey, maybe some of your friends can do it? How about you?"
"You know, it's a shame, I haven't slept for 48 hours."
"Too bad. Maybe someone else? You?"
"No way. You don't have a million dollars."
"What are you talking about? It's right here in my suitcase."
"I don't believe you. You're a liar."
"Er, okay... Anyone else, perhaps? How about you? You're a professional athlete, aren't you?"
"Oh yes, I am. That's why I don't need your stinking million. I'm making big bucks, man. Stop bothering me."
"What's wrong with you, guys? Does no-one want a million dollars? How about you, you look poor?"
"Well I would like the million, but the road is rigged, your stopwatch runs too fast and you'll just keep throwing sticks under my legs. But hey, what if you have a panel of judges look at my medals and decide if I deserve the million or not? That sounds fair to me."
"Is there
anybody here who can run the damned thing?"
"I, I can do it!"
"Great! Get going!"
... runs for 30 meters, then collapses.
"*wheeze* *wheeze* I'm sorry. I ran yesterday and I'm all exhausted. I can't repeat it right now."
"That's okay... Why don't you go home, practice and rest as needed, and try again when you're ready? You can try as many times as you like."
"That's not fair. I'm telling you I did it yesterday. You should just give me the money."
"But... you didn't do it!"
"I told you, I did it yesterday! But I see... you're just trying to weasel out of it. Even if I did run it, you would just deny it. You're a fraud."
"Come on, guys! This poor fellow is tired, but surely there must be someone who's not tired? You said you do it every year, some of you even get paid for it..."
"Let's go home, this jerk is a fraud. And on top of that, he's insulting us by questioning our honesty."
"Come on! Is there no-one who can do it? Not a single person? Hey! Come back...!"
...
"Well if you find someone, tell them that I'm still waiting here, okay? ... Hello...?"
