Words that sound funny in German

Sometimes you are in the grocery store, minding your own business, only to be confronted by:

(I think Muffins Hell means Light Muffins)

Or maybe you are at the Garden Center when you see:

Nutzpumpen has something to do with hoses (literally, utilizable pump). Sure.
