Is there sugar in bread? I know the yeast eat it when they make bread. Just put a stick on butter on the stove and chop up some weed very finely and put it in. Let it simmer on medium heat for 10 minutes or so then strain it through a cheese cloth, stick it in the freezer (or ice bath for extra credit) and let it cool down. Once it is somewhat solidified so the point where it doesn't spill out and such, put it on your toast.
Or you could use a spoon and spoon liquid artery clogger over your toast.
