Fake Mexican Tourist Blues lyrics

Hey, mister, would you like my sister
Her name is juanita,
I think. youd like to meet her.
Shes a little bit risky,
Drinking always whiskey.
But shes really a tiger
Take you right inside her.

Hey, mister, got another sister
Her name is dolores
She likes pretty colores;
Shes a little bit silly,
Eating always chili;

But shes very sexy,
Take her home in a taxi.

Hey, juanita, juanita banana
Hey, juanita, would you hold my banana;
Id like it now, I dont mean manana.

Hey, brother, what about my mother
Shes only just forty
Shes especially naughty.
She knows a lot a tricks,
More than the younger chicks.
And if you dont like my mother,
I got a very nice brother.
