Dandelions: Beautiful Flower or Killer Nuisance?

Dandelions are often touted as annoying weeds that need to be erradicated, but there are others that feel that their yellow, then brown, then white, then balled appearance is actually quite pleasant. They are flowers that don't need to be purchased because they appear wether you want them to or not and can also be mixed into a disgusing salad by a person you wished you never engaged in a conversation in the first place. On the other hand, they are disgusting weeds that come from seeds blown into my yard by the inaction of my asshole neighbor.
