"Wacky tobacky" dat is prescribed by a snake-oil doctor.
If you ask a phony physician why he is recommending dat you try QUACKgrass for your ailments, he will likely just "duck" da question.
Quackgrass is drug related, as you can get addicted to it, and if you have not had it for a while you also get withdrawals.
I am addicted to my quackgrass where is she, i want her now.
