I hate these 'jokes' which are, usually, perpetrated by a certain type of Middle Aged man. If there's an audience they glance around to make sure that everybody is suitably amused by their wit. I make sure that I stare back with cold, dead eyes.
I have to agree with this. So many men (often aged 40 to 60,) think they are fucking hilarious. My DH is a dear man, but his 'joking about' really gets on my tits, and he thinks he is soooooooo funny, and yeah, he says something 'funny' really loudly and looks around to see if someone is looking.
One example is when a cashier asks 'would you like cashback?' and DH ALWAYS says 'ONLY IF IT'S FREEEEEEEEEE!' 
Every.
Fucking.
Time.
He thinks he is hilarious and quirky. The (female) cashier thinks he is a cunt. When I say 'ffs you say that every time! It's not funny...' He says 'well SHE smiled!' What he doesn't realise is that she is being polite. Deep down she thinks he's a nobhead, and he's the 50th middle aged man this week to try and be funny.
It's always with women too, never men.
But so many men (in this age group,) are the same. My daughter and her young female pals (aged 20-30) report tales of men like this - often at work. Middle aged men (usually portly and balding,) who think they are HILARIOUS and quirky, and that all the laydeez think they are amazingly charming and funny and attractive. With their practical jokes and windups.
Even DH comes home some days from work, telling me how he wound up this 18 y.o. young woman ('Megan') at work up by conning her into believing some bullshit. And then says how 'me and 'Megan' have such a laff at work.' ('Megan' is approx 35 years younger than him and thinks he is a massive nob.) I know this because every young female I know thinks middle aged men who try and be funny are sad cunts.
Why do middle aged men do this? WHY? Are they trying to convince themselves that they've still 'got it!' And that the laydeeez love 'em? 
Fucking annoying. Coz on the rare occasion I do it, DH just looked annoyed. And although he thinks it's funny when he plays a practical joke on me, he gets really arsey if I play one on him. Funny that isn't it? Practical jokers never like it when you turn the tables on them!
