German Girlfriend Distraction

Alright, listen up, you big silly bear! The joke here is all about how words sound. The guy is with his 'German girlfriend', right? And she keeps saying 'her age'. Now, in German, the number 'eight' is pronounced 'acht', which sounds a lot like 'age' in English, especially if you're not used to the accent. So, she's probably just being a bit enthusiastic, counting or something, saying 'acht, acht, acht' (eight, eight, eight), but the guy hears 'age, age, age' and thinks she's just loudly declaring how old she is over and over again. You, on the other hand, probably just hear 'honey, where's the picnic basket?'.
