That’s what I’m certain British people call “mahed pototoes”. And if they don’t, they should. Sounds like something they’d say over there.
We don’t.
bugger.
Mahed Pototo does, however, sound like the name of the leader of some small African nation.
Having said that, I do agree that “mashy pots” is the sort of twee nonsense we often come up with.
What, like baked spuds? 
Smashataters. Duh.
Good times.
URGENT BIUSNIESS PROPOSITOIN
From: NZANGA JOSEPH POTOTO
Attn: Managing director/CEO
DEAR Sir,
I am the first son of the late Mahed Pototo, the former Chairman to the Contract Review Panel that was inaugurated by the President of the Federal Republic of Nigeria.
I am presently under protective custody in South Africa as a political refugee. I got your contact during my search for a stranger that can cooperate with me in this mutual transaction.
I want you to note that this business will benefit both of us. however, you must confirm your ability to handle this because it involves a large amount of money. The money (28 million US DOLLARS is my share of my father’s estate…
Now THAT is funny!! 
Mangetout, thanks for the first great laugh of a deplorable week. And BTW, it is also the first time that I have not called you Mangetrout in my mind. Have you changed your name recently, or have I just thrown a wobbly?
No, I have always been Mangetout; there was an impostor by the name of Mangetrout, If I’m remembering correctly, but he only made a handful of posts before the mods tracked him down and sold his kidneys.
MANGETOUT, you are one funny dude! I’d kiss you if I could reach you.
