A man walks into a bar with a small frog sitting on his head. The bartender looks up and says, "Hey, what's with the frog on your head?"
The man replies, "Oh, this little guy is my lucky charm. Every time I come here with him on my head, I win big at the roulette table."
Intrigued, the bartender decides to try his luck and asks the man if he can borrow the frog for a few minutes. The man agrees and hands over the frog.
The bartender places the frog on the roulette table and bets all of his savings on black. The wheel spins, and sure enough, the ball lands on black. The bartender is ecstatic and starts cheering, thinking he's hit the jackpot.
But suddenly, the frog lets out a loud croak and jumps up onto the roulette wheel, causing it to go flying across the room and shattering into pieces.
The bartender is left in shock, staring at the mess on the floor. The man walks over, picks up the frog, and says, "I guess he's not very good at letting others have the spotlight. Looks like he can be a bit of a show-off sometimes."
The bartender can't help but laugh at the absurdity of the situation, realizing he won't be trying his luck with a frog on his head anytime soon. And as for the man and his lucky charm, they left the bar with a big grin on their faces, ready to find their next adventure.
