Perhaps you could start a thread on the worst predictions ever, football elated and non-football. Some could even be personal as in your example.
One of the all time classic of predictions is this one: "We don't like their sound, and guitar music is on the way out." Decca, in 1962 when rejecting The Beatles
'John Lennon when asked if Ringo Starr was the best drummer in the world? "Ringo's not the best drummer in The Beatles" Also I liked John Lennon's answer in a hard days night Reporter "How did you find America?" Lennon "Turned left at Greenland"
When The Rolling Stones landed in the USA for their first tour after Satisfaction was released, Jagger was asked if he was satisfied: "What do you mean? Sexually? Financially? Philosophically?" "How about all of them" "Sexually satisfied, financially dissatisfied and philosophically trying!"
WGS "Am I the right man to take Southampton forward? No I think I'm absolutely useless. I told them to go for George Graham." or
"this is what happens, Larry. This is what happens, when you **** a stranger in the ass!" Larry Sobcheck (The Big Lebowski)
"This management lark is simple. If I buy every player who's played well against Liverpool, then there will be no one left to play well against us, and we will win the League" Brendan Rogers (probabaly)
Dead right - I went to a gig by him. Brilliant music, but no engagement with the audience and buggered off before the end without saying goodbye. Love his music, not the man!!
When Shearer left Saints I said that he'd never make it as he tried hard but wasn't a good finisher!! To counter that, after beating Vill in the 3rd round I predicted us to win the cup in '76 (and I wasn't drunk and I put a bet on, only 50p but, hey, that was like £1m in those days!).
I've missed more than 9000 shots in my career. I've lost almost 300 games. 26 times I have been trusted to take the game winning shot and missed. I've failed over and over again in my life. And that is why I succeed. - Michael Jordan If winning isn't everything, why do they keep score? - Vince Lombardi
When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity. Albert Einstein
I may be drunk, Miss, but in the morning I will be sober and you will still be ugly. Winston Churchill
Ahem. Read my signature for the definitive version. I wrote it down listening to Ronald again and again just to get it dead right.
My favourite of his was when a lady in the house said to him: "If you were my husband, I would poison your tea.." His reply: "And if you were my wife, I would drink it" Or very similar.
