Joel, from the beginning skit of MST3K Fugitive Alien:

"Well anyway, hi there folks.  You know I'd been having trouble with
velvet leaf, uh cutworm and uh foxtail and well that's when the 
representative from Monsanto came out to my farm.  He recommended a
pre-emergent, inferral mixture of Lorsban with Atrazine in a tank mix
and I told him to get off my land."
