A tangent is a line perpendicular to a radius of a circle, or something like that. Since the line goes "off of" the circle, you clearly go "off on" a tangent. Going off on a tangent in a discussion is frequently used to derail the conversation, much like a penny can derail a train if that penny has an explosive charge attached to it. Therefore, a tangent is like a penny with an explosive charge. Explosive charges can also be used to open bank vaults and demolish abandoned buildings, and can come in very handy if you need to ruin a face.
“Buildings are abandoned because no one is using them.”
There is debate on whether or not buildings are like children, which can be both abandoned and abused. Abused and abandoned children can potentially become the dredges of society, like soda jerks and accountants. These lowlifes frequently take up residence in abandoned buildings in order to escape from the pain of reality or from the law.
“If a building has people in it, you can't very well call it "abandoned" can you?”
When people are hiding from the law, the law will sometimes employ dogs to pursue them. Many dogs, such as bloodhounds, are "scent hounds" and can smell the fear of the criminal element from miles away. In order to avoid detection, criminals will find a moving body of water and will swim or wade upstream. If they are lucky, the water will smell like shit, throwing off the hounds. This is where the phrase "Up Shit creek without a paddle" originated from.
“The only thing worse than being up Shit Creek without a paddle is to drink from Shit Creek and pass out, leaving your prone body at the mercy of vicious attack dogs.”
Another option for the criminal who is on the run is the use "kippered" or "red" herrings to lead the hounds astray. Speaking of stray hounds, if you want to get a new pet, check out your local animal shelter before going to the expensive pet shop. Either that or you can breed your own dogs.
“Oh, she likes to breed, eh? Likes to breed? Knew she would, nudge nudge.”
Before breeding any animals, including humans, it is important to understand how the animal's reproductive system works. This knowledge is freely available to anyone with enough alcohol. For more details on this process, please read about animal husbandry. Of course, one cannot bring up husbandry without bringing up marriage...
“Animal Husbandry doesn't mean what you think it does, foo'!”
