I get my food on aisle six and my best hunting is done along the back perimeter walls of most super-markets, but I'm guessing nature is telling me that the ones with all the little barbs by your thumb says that your best bet is to eat the grubs that ate the "carrots" and let them figure it out; but, given the choice, I pick the ones by the blade tip.
BTW, the mini-bushboot is one of Andy's "killer patterns" to keep with the thread's theme.
Oh, and your post needs the "now you know" line so I know which one not to eat. Because all you did for me is tell me to eat dandelions which will only make my mouth taste bitter. (I calc'd it out once and I had to eat 14.7 pounds of dandelions to equal the 1300 calories that I spent bent over picking dandelions for a 1300 calorie day. That my friend caused me immense intestinal distress just thinking about it.) So, I figured it was better to just suck on a rock with a dandelion and imagine it was one of those super-sour candies my kids used to give me thinking that I don't know what it is, but I do. However, I play like I don't and then they laugh and laugh thinking that they got one over on their old man. One day they'll understand when Grandpa gives their kids a bic lighter and tells them it's bottled up fire-flies and its up to them to set the fire-flies free---payback! (Kidding!)
