These are simply a form of home-made preserve. To be more precise, oily leathers are a type of marmalade where the "bits" in the marmalade are entire fruit skins. The name comes from the appearance and texture of these skins. Oily leathers are considered something of a delicacy, and are surprisingly hard to make (at least, such that the end product is edible). Futhermore, as they are an acquired taste, I advise you to approach them with caution.

Meanwhile, what's a tablet contestant?

One who takes an aide-memoire to consult in any potentially complex situation, such as being in bed with someone.

Just what are lucubrations, really? Especially epistolary ones.

I must admit that this took a while to come back to mind, but it finally did! If you ever went to Sunday school I am quite sure that this will ring a bell. epistolary lucubrations is the raw fear experienced by those of little faith when asked to quote a text from the letters of the apostles - it seems (for some as yet unexplained reason) to be more severe should that citation be sourced from the book of Luke.

Now, I came across this the other day and, says he hiding his head in shame, do not know what it means; we all know what "a penny for your thoughts" means, but what about "A quid for your pro"? Surely nothing to do with ladies of the night - or is it?

This was an early attempt by the World Health Organisation to stop mosquito bites by jamming their proboscis with a concoction of chewing tobacco and DDT. The "quid" in question proved very popular with the insect fraternity and when sprayed in the area was rapidly sucked up the proboscis(or Pro) however they used the human population as a mobile spittoon and the resultant spotty complexion resulted in wasting millions of pounds of a false measles epidemic.

During my wasted years in the local library I borrowed a book about nutty seepage which I lost after page six whilst the expedition was still being organised. What happened and what was it?

A hazard of testicle piercing.

What is a lizard shiner?

Something I'd rather not know to do with circumcision rituals.

Is this now a Moribund Entertainment?

By that, do you mean
a Norwegian Blue?

A Norweign Blue and a moribund entertainment are referring to the activity but as seen from across the gender divide.
A norweign blue was a prank developed by the female students of Oslo University. During rag week they stood by traffic lights in the buff, when the front cars stoppped male drivers were then offered a bucket of cold water, a soapy sponge and 30 seconds to rub the student down.
What Raak refered to is the jealous wives in the passenger seat death like, arms folded and grim ashen faced not looking.

My brother who is more widely travelled is rumoured to have had a great time with a Swindon plank is this possible?
