[DBZ] How in God's name did Mr. Satan make anyone think he beat Cell?

Also, why didn't Goku and his team try to tell the truth that they beat Cell and prove that Mr. Satan was full of it?

Mr. Satan is good at putting on a strong front and he is a talented fighter. While not quite on the level of the Z Fighters he would beat most people on Earth. He won the 25th Budokai fair and square.

The idea that the current world martial arts champion could defeat Cell wouldn't be that bard of a sell. Especially when he filled people with rhetoric that Cell didn't have any actual powers and was just using explosions planted ahead of time.

The Dragon Team doesn't desire fame and have no reason to take it from him. Least of all the actual person who beat Cell, Gohan doesn't even like to fight at that stage. The last thing he would want is to be known as the little boy who beat Cell and is the strongest person on Earth. Mutually none of the others want that kind of prestige. If they wanted they could beat him at a Budokai whenever. But the money and fame aren't why they fight.
