There was an old codger called John
who's strides were exceedingly long
he'd not hitch them up
for his belly was such
that they wouldn't slide over his thong!
A young lady most awfully dressed
went off to her job in a vest,
her colleagues all stared
when she walked down the stairs
for the poor girl was all knickerless!
