Work Day Grey

Xs in boxes that is my job,
Its a dishwater drab,  gun metal grey
Utterly boring work day

Ps and Fs in boxes too
That's all there is to it
Not much to do

Speeds and percentages
That's in there too
still not thrilling, but what can you do.

Nothing is perfect that's what they say
it's a dull job but at least I get paid.
