Diglett sticks out like a sore thumb, literally. People walk all over him because he deserves it.
When a Diglett evolves into Dugtrio, it looks angry all the time because it's forced to live with 2 other Digletts for the rest of it's life.
My favorite Diglett joke, I tell it to every Diglett I meet: What do you call a Diglett 12 feet under? Doug. What do you call a Diglett 6 feet under? Douglas. What do you call a Diglett slightly protruding from the ground? Pathetic.
Samurott's near perfect blend of great stats is horrible. Being able to learn all water-type hms is terrible. Being able to deal and take high damage is the worst possible combination for a pokemon. Samurott sucks. :p
What's worse than getting dumped? Being forced to listen to some 10 year old rage in his mic on BO2.
