Self-driving Golf Ball
From City AM of
the UK
"I think some
people will say that Donald Trump has a secret ball like this, and that's why
he wins every time when he plays golf," commented a defensive POTUS.
"Others will say that Donald Trump is a cheat and a liar, and that's how
he wins every game. And many other stories like that, my fellow Americans. The
reality, of course, is that POTUS is the biggly greatest, authoritatively most
biggest, and all-time brightest, bestest golf player that has ever played this
Sport of Kings. Simple. No one says God fakes it. So, why always
accuse Me of nasty things?!"

GIZMAG: A dog's view of the world
"I hadn't realised Rex, my Rottweiler, loves sniffing any turd he spots in the garden or in the street: he never stops. Also, he licks his balls on average 3 times an hour: I need to tell Brenda, my wife, because she loves it when Rex licks her face. She might have a re-think.
Another thought that's crossed my mind is that I'd like Brenda to wear one round her neck: I'd like to see the world through the eyes of a woman. I've never done that before.
It might be interesting. I mean, how do you know what they think, on a daily basis? A bit like Rex, so to speak. It's a mystery. It's not like you listen when your wife talks to you, most of the time -- I mean, life's too short and we're all busy, innit?" commented Ralph Plank, a builder from Peckham (London).
