My two cockatiels, pictured above, I bought them from a pet shop in July of 2001 and when I got them home I was looking at them and, just out of the clear blue shy I thought of, Cheech & Chong. Since 2001, the only words that I have been able to teach them to say is "Pretty Bird" and if anyone comes to the door or in the house they start in with "the Sexy whistle" which I also taught them. I've tried and tried, over and over to teach them to say "Bad Kitty" when the cats get on their cage but to no avail all they do is set and stare at the cats and just dare them to put their paws through the bars. And yes! that has happened a time or two. HAHA!
