Kirkland Homogenized Milk

Did you ever buy a carton of milk and find that, upon pouring the milk into your cereal bowl, it spills out onto the table?  At the same time the milk runs down the side of the carton and appears to drip out of the bottom.  Is this spillage a temporary aberration in the steadiness of the wrist?  (But it spilt for Natasha as well.)  Is it a design flaw in just a few of the cartons?  If so, exactly what went wrong on the assembly line?  Or does the product work this way on purpose?  Does there exist an angle at which the milk can be poured without spillage?

Does this mean we won’t all evolve into uploads?
