Krampf literally means "cramp," like a muscle cramp. However, it can also be used metaphorically to mean a struggle or a difficult effort.
In the song, the singer first uses it literally when he says, "Und kriege einen Krampf" (And I get a cramp) while swimming. But then, he immediately follows with "Vergebens ist mein Krampf" (My struggle is in vain), showing the double meaning and how a physical cramp can represent a larger, futile struggle. This clever play on words makes it an interesting and memorable choice.
Have you ever thought, "I'm my own best friend"? This hilarious song by German comedians Otto and Sid takes that idea to an extreme. The singer proudly declares, "Ich bin mein bester Freund" (I am my best friend), and then describes what this "friendship" looks like. If he's drowning, his best friend (himself) will just stand on the shore and wave goodbye. If a robber attacks, he'll hide behind his friend and then run away. It's a funny and sarcastic look at being selfish.
But the song takes a sweet turn! After complaining he has to eat a whole tub of chocolate ice cream alone at a party for one, his friend suddenly appears, eager to share. The song's chorus changes from "I am my best friend" to "Du bist mein bester Freund" (You are my best friend). It's a playful reminder that while it's good to rely on yourself, true friendship—especially when it involves ice cream—is even better.
