First joke in Spanish!

I was eating dinner with my Guatemalan family yesterday (super late, because I passed out for 8 hours right after I got there). Mama Cony, mi madre guatemalteca, has all these cow tchotchkes, including a salt and sugar dispenser that look like beatifically reclining cows. However, she had washed them earlier, and they were on their sides. So, I said, "Ay caramba! Tus vacas!" And started setting them upright, like they were injured or something. All present were at least mildly amused.
