Out here in Nv we call em goatheads...and boy you know it when one gets stuck in your shoe!!! *ow ow ow* I hate it when the dog picks em up and you *try* carefully to get them out but the dang things wont come out without tugging and most of the time at least I end up with a stab wound in my fingers as a result!
And they are imposible to get off of blankets lol.
