Oh, boo-hoo! Let me play a sad song for you on the world's smallest violin.
The world's smallest violin is an instrument played by Mr. Krabs three times in the episode " Squilliam Returns."
The world's smallest violin is essentially a regular violin except it is far much smaller. Despite its size, it still sounds like a regular-sized violin. The song played on the violin is "
Woe is Me!"
Role in episode
The world's smallest violin is played a total of three times in the episode "Squilliam Returns." Mr. Krabs first plays it after hearing
Squidward's story on how he must beat Squilliam.
The violin is played a second time after Mr. Krabs hears Squilliam telling Squidward that he was a cashier too (which was false).
The violin is played one last time right at the end of the episode when Mr. Krabs appears by a saddened Squidward. The latter replies by saying "Would you get out of here?!"
Mr. Krabs playing the world's smallest violin has some hits on YouTube, such as remixes and longer versions.
Mr. Krabs playing this violin might be a reference to the TV series where Mj. Margaret Houlihan rubs her thumb and forefinger together and asks "Charles, do you know what this is? It's the world's smallest violin, and it's playing just for you." M*A*S*H and the movie  when Mr. Pink is arguing about tipping the waitress, and he says " Reservoir Dogs You know what this is? The world's smallest violin playing just for the waitresses."
Judging by the scale measurement to Mr. Krabs, the violin is approximately a third of a centimeter, making it truly the world's smallest violin. However, if it were real it would play at a much higher frequency.
The smallest violin can be heard in some episodes but in a slower and lower tune.
