We do notice you Americans struggling at times, here is an aid to English grammar for our cousins :-
Tire - this is not a round rubbery thing that bursts, it is what happens when you're young after shagging all day
Labor - Correctly spelt labour, this is what you should supervise other fckrs doing
Center - Centre, the middle of a popsicle, useful when encouraging young girls into your van
Luster - This is not longing to shag your wifes sister but accurately describes what hair I have left, Rob's hair has a lustre about it?
Plurals are with an S not a Z (pronounced zed not zee)
Rob is available for consultation at reasonable rates to all bona fide idiots.
