Dumber than advertised.
Doesn’t have the common sense that G-d gave lettuce.
Biscuits and gravy without the gravy.
Couldn’t spell Cat if you spotted him the C and the A.
So dumb he could fall into a barrel of tits and come out sucking his thumb
Couldn’t find his arse with his own two hands.
One beer short of a six pack.
Two coupons short of a toaster.
I swear he rides the short bus.
Sits behind the driver and licks the windows.
IQ of a houseplant
Not very smart.
Wears a pony tail to hide the valve stem.
Nurse dropped him on his head at birth.
[enters booth, pulls lever, opens curtain & leaves]
Couldn’t find his ass with both hands AND a road map.
I don’t think you quite get what we’re doing here…
Unencumbered by native intelligence
Dumber than bowl of mice.
Low albedo.
If his bus were any shorter, it’d be a lawnmower.
Room temperature IQ and I am not talking Fahrenheit.
I do like that one.
Two breaths short of a whoosh?
Doesn’t know his ass from a big green rock.
Couldn’t find his ass with both hands and a flashlight.
The elevator only goes down.
The factory’s running, but it makes something different now.
Every village has one.
If we had seventeen more of him, we’d have a golf course.
Thick as a whale omelet.
(Blackadder)
