I'm supposed to have another one somewhere

All men certainly have, in the same vicinity, when they are with an attractive lady.

[Sir Tigger KC]

There are plenty about who seem to have their brains in their 'arris! 

Not naming any names like.   

[BazaJT]

Unfortunately for me Rods2 my memory isn't that good

[Bigron]

I was expecting Lizzie to come up and say all women know where men's brains are - first or second! 

Ron.

[BazaJT]

Ah,now if Lizzie were to volunteer I reckon she'd be able to re-start my memory Purely in the interests of science of course

[Bigron]

That would only make things hard for you, Baza! 

Ron.

[Doctor Gollum]

That would only make things hard for you, Baza! 

Ron.

Difficult  perhaps, maybe even awkward...

But hard? Not likely...
