Let's Do a Test

Mashed potatoes in her hair Worked better than the pudding. Where were spuds, the waves are fair; The other's not so gooding. The spuds had gravy thereupon; She spread them on just so. The choc'late pudding soon was gone; On t'other side did go. Was it spuds that made the waves, Or was it gravy, too? Would any gravy work as well As chicken flavor do? If the spuds are from a box, Do they do just as well As freshly peeled, whate're the cost? Please come and sit a spell. We need to test a few more things-- The whole kit and kaboodle-- To see what best results 'twill bring If used upon your noodle.
