Stanley's a rat and a fast one at that
From bulkhead to bulkhead in four seconds flat
He's come and he's gone 'fore an eyelid could bat
But he'd do it much faster if we had a cat.

One flashing run and his visit is done
Stan never lingers to join in the fun
Our hospitality he'd rather shun
But he'd stay a bit longer if we had a gun.

I raises my cap to this beady-eyed chap
Who needs no compass and carries no map
And don't know what it means to get in a flap
But we'd bloomin' soon show him if we had a trap.

When does he doze? Well, nobody knows
Night and day he keeps on his toes
I don't suppose his eyes ever close
But he'd sleep for ever and ever and ever
if we had a high pressure hose.

For those of your born in 1912 (maybe a bit dead for MC), 1924, 1936, 1948, 1960, 1972, 1984, or 1996 (maybe a bit young for MC) You are all Rats (Chinese Zodiac).

Rats are shrewd, quick, alert, and born opportunists.
