I would stretch Swift's hypothesis further by stating that (smaller) funny words (in a fixed language system) have more force due to their portability as well as due to the motion they exhibit.
Smaller words are more easily remembered; words that are both useful and frequently utilized travel easier through a language system. This behavior of words mirrors molecular and subatomic processes in that some words can be more easily displaced from one point of view to another.
"I feel that teaching linguistics at an introductory level for all those years put me in a position to talk about the intricacies of words on an authoritative but jovial level anyone can understand and enjoy." Dr. Beard.
For those with a penchant for language, reading Dr. Goodword's list of funny words feels like a Saturday morning spent reading the Funnies.
Imagine, if you will, that you've just poured yourself a bowl of Canoodles, that sugary blend of tubular-shaped (nanotubes), those fruity flavored Miniaturized bites with that deliciously intense artificial flavoring that tickles every molecule in your body, leaving your central and peripheral nervous system in an enhanced state of alert awareness. Yum!
It's a good thing you just ate a bowl of Canoodles, because if you attempt to read a list as long as the one that follows - especially through the uncomfortable glare of a computer screen - you are going to have to be alert enough to stay awake, then exhibit enough endurance to get through the task, set aside the required time to read online - which takes approximately 25% longer than reading from printed material - and finally, find the motivation within yourself to complete this task knowing perfectly well you have other, more important things to attend.
Without further ado...(thanks Shakespeare)
