Have you never tried or something?
A man walks into a pub. He sits down at the bar. He takes out a small piano and a frog, and puts both of them on the bar. To the bartender's surprise, the frog starts playing the piano. The man then pulls out a rat and puts it on the bar. To the bartender's further surprise, the rat starts singing. Another man at the bar turns to him. "Say," he goes, "that's a great act! Would you mind selling them to me for $25,000?"
"No way," says the first man.
"In that case," the second man continues, "would you sell me just the rat for $20,000?"
"Well," the first man says, hemming and hawing for a moment, "alright." He hands the man the rat, then receives his $20,000. The lucky owner of the rat walks out of the bar, satisfied with himself.
"What the hell is wrong with you?" asks the barkeep afterward. "Why did you break up a million-dollar act like that?"
The man at the bar just smirks. "The frog's a ventriloquist."
