Slight NSFW and GerIta (I think)
Italy found a stray cat and decided to take them home with him, he then introduced the cat to Germany, but the cat got scared of Germany and ran away, causing Italy to cry, so Germany offered to find the cat for Italy just to get him to stop crying.
While Germany was searching for the cat, he suddenly heard Romano's voice.
"Hey, potato bastard, what are doing peeking through bushes like a pervert?"
"Ich suche die katze."
"YOU WHAT?!"
Later...
"Germany, you're back! Did you find- Why do you have a black eye?!"
German: Ich suche die katze = i'm looking for the cat
From what I've heard it would sound a lot like
Italian: Io succhio il cazzo = I suck the dick
