The longer I’m in, the stronger it will get.

An Oddly Priced Fish Shop

A fish shop with odd pricing sells fish for the following prices: A trout costs $20, a salmon is $19, and a plaice comes in at $16. Using their pricing logic, how much would they charge for a mackerel?

$13. The price is calculated by using the position in the alphabet of the first letter of the name of the fish. An Albacore would be $1, a Bandfish would be $2. Note, I do not recommend using this pricing strategy unless you find yourself with an assortment of cheap Zebrafish.

Only One Color, But Not One Size

Only one color, but not one size,
stuck at the bottom, yet easily flies;
present in sun, but not in rain;
doing no harm, and feeling no pain.

A shadow.

Here Comes My Wife and Daughter

Two men are standing on one side of a bridge and two women are approaching them. One of the men says, “Here comes my wife and daughter” to which the second man replies, “Here comes my wife and daughter”. If they have not married the same woman and the women aren’t pregnant, how is this true?

The men are widowers and married each others’ daughter.

A Slight Inclination of the Cranium

A slight inclination of the cranium is as adequate as a spasmodic movement of one optic to an equine quadruped utterly devoid of any visionary capacity.

Translate this rather strange sentence into one that is more sensible.

A nod is as good as a wink to a blind horse.
