Advice for Valentine's Day
(Dave Diamond)

Beware the sneaky Married Man,
He will ensnare you if he can.
Although with age and fat he creaks,
Illicit love he vainly seeks.
His wife, you'll often hear him tell,

ADVICE FOR VALENTINE'S DAY
(Dave Diamond)

Beware the sneaky Married Man,
He will ensnare you if he can.
Although with age and fat he creaks,
Illicit love he vainly seeks.
His wife, you'll often hear him tell,
"Can't understand". Alas, too well
She understands, but has the sense
To trust in his incompetence.
He shakes with lust, he reeks of vice,
In fact he isn't very nice.
Yes, yes, it's true, and I'm that swine,
But please, please, be my Valentine.
