There is a Spanish joke,
Ella es mi amiga vieja, disculpe, mi vieja amiga.
The joke basically says, "She is my friend that is old, excuse me, my old friend", making fun of the person's age. Would there be a way to translate this into English?
Of course, saying something like "She is my friend old..." doesn't work in English, though the joke does also work in languages like French. The translation I wrote may be considered to work, but I was looking for something smoother.
Edit: my attempt:
She is my old af friend, I mean my extremely old friend, I mean my old pal.
