¡Feliz Cumpleaños! And many happy returns.
Wishing you a Green Toad today. Sapo verde a ti. That is what a lot of the kids sing here on birthdays, it sounds like the Happy Birthday song. They know the words aren't correct but have fun wishing you a green toad to the catchy tune of the English birthday song getting laughs as they sing it to you.
So, Sapo Verde a Ti, Cheenagringo! I hope you have a nice fiesta to celebrate YOU today. And this is that year of the Beatles song when you're 64. Celebrate it.
