"Three Brothers" joke

Three jewish israeli brothers come to america. They each get jobs.
The first one is a singer. He learns to say, "Me, me me me me!"
The second one is a waiter. He learns to say, "Forks and knives, forks and knives."
The third one owns a candy shop. He learns to say, "Goody goody gum drops!"
One day a man is murdered. The three brothers are at the crime scene, and they're being questioned.
One cop says, "All right, now who did this?"
The first brother tries to point out the man, but the only word he can say is, "Me, me me me me!"
The second cop says, "What did you kill him with?"
The second brother, trying to prove his brother's innocence, says, "Forks and knives, forks and knives."
Finally, the third cop says, "All three of you are going to have to come downtown with us."
And the third brother, trying to protest, says, "Goody goody gum drops!"
