If not, here's what can happen. . .
unclear messages. . . What do Jedi squirrels have to do with back pain?
inefficieny . . . though you have to admit
this design is clever
poorly built products . . .
(the perfect haunted house!)
poor designs that make you shake your head . . .
road blocks in your students' pathway . . .
