A scientific term. Tumblr's Law states that when a Tumblr user directly mentions or implies that a joke is funny, the joke is no longer funny. This can be commonly done through saying that a meme is hilarious, but can also be completed through such an action as laughing.
When a Tumblr User (commonly self-identified by a person with an active Tumblr account) laughs at something that could be considered humorous, every living being within a 5 mile radius instantly stops feeling joy for a short time. After this event, the joke is no longer funny, and it can no longer be referenced.
The only potential Tumblr Users then have for humor is in creating jokes, but hopefully it is not attempted on Tumblr.

Get the Tumblr's Lawmug. Its for a group of boys who believe in their own laws and act as both judge and jury for the actions of the people around them, even if they are not part of the group of boys.
Essentially a circle jerk of guys who are in their own fantasy.

Get the theif in lawmug. "You can sit and watch a documentary-video on YouTube for extended periods with little or no advertisement-interruption, but then just as soon as you turn up da speaker-volume and go into da next room to take a dump, a whole bunch of ads will come along and you'll hafta endure listening mostly to them while yer poopin', rather than da video-commentary you'd wanted to hear.
Due in large part to da pesky "Murphy's Law of YouTube Ads", a few more-affluent citizens who live alone actually hire a full-or-part-time "Jeeves" for da sole purpose of being an ad-skip assistant.
