I must protest. Electric nose hair trimmers are a godsend for people like me who grow nose hair like the Dutch grow tulips.Traffic lights?! Ah yes much better to let people just drive through every intersection and slam into somebody. Or have stop signs at every interesection. Now THAT will speed up traffic.
What are you people thinking?!!!!
Most worthless invention of the 20th century definitely has to be the teenager. Before the 20th century we didn't have a whole class of unemployed, whiny, self-absorbed, pubescent fools. When you were old enough, they gave you a shovel or a pick or whatever, and you were an adult. The concept of "teenagers" as a class, as a purchasing bloc, whatever, is 20th century in origin, and worth than useless, it's harmful.
Old fart, ain't I?
