Anybody ever had to deal with this?

This is a weed that is an absolute pain in the a$$ to deal with.
Listed by the state of California as a noxious weed, and by quite a
few others as well, this little $#%^&! is not only taking over my
garden, but is also creeping into my dreams....

Anyone had any run-ins with this little $&#!? Any ideas how to
eradicate?
