I always find "The Constant Lovers" funny. It's so OTT that I can't believe it was ever meant to be taken seriously.

Also there's a line in the penultimate verse of "MY HUSBAND'S GOT NO COURAGE IN HIM" that sounds like necrophilia every time I hear it.

HARTLEY MORRIS have a habit of changing "Shepherd Swain" to "Shepherd Neame" (a Kentish Brewery) whenever they sing "The Holmfirth Anthem" - I now find this part of the song funny, even when it is sung properly.

Finally, "Pleasant and Delightful" has so many alternate versions and lines, that it's hard to stick to the original. I always end up singing "The sharks they played melodeons", "and the finger came too" etc. - and can't resist producing the "POP" for "a ring from off her finger she instantly drew".
