Shaytards 

The concept began in March of 2009, when Shay's viewers were complaining that he wasn't posting videos very often, and Shay began to feel bad. As sort of a "punishment", he decided to post a video everyday for a month, and if he missed a day, he would delete his famous Shaycarl channel. It became a year. Which became just everyday.

Through watching the videos, we learn many things about the Tards. Shay and his wife, nicknamed Katilette (or mommytard) have 4 children. For security reasons, Shay and Katilette do not purposley let out their childrens names, so they are given "tard" names. The oldest child is Sontard who is six, five year old Princesstard, three year old Babytard, and the newest edition, two month old Rocktard. They also have a dog named Malachi.

These videos have become part of many people's daily life, and routine. Many of their videos have delt with serious issues, like when Princesstard realized that someday she was going to die. Or when Rocktard was born. We've seen them all laugh, cry, scream, but what sets them apart from most families is how close they are. They are always laughing and having fun with each other, and they love each other more than anything in the world.
Mike: Yoo, did you see the new Shaytards video?

Carol: No! What happened?

Mike: Sontard fell off his bike and landed on babytard!

Carol: No way! I'll have to watch when I get home!

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
