When I was in Bali at a bird park thing there was a lady doing a demonstration with a bunch of parrots and after she finished flying them around she walked around giving them to everyone who had hands ... she had taught one of the parrots to lie on it's back on command, and she would put it into your hands like that. Just like - here, have an upside down parrot! And you're like ... oh hey, thanks, I always wanted one of these OMG PARROT ON IT'S BACK. And if you're me, you promptly forget any and all relevant witty Monty Python cracks because omgparrot. Alas!

Anyway, I bet that's what happened to these folks. Uncannily, it's the same kind of parrot and the lady has the exact same expression that my mother did ...
