Did you get the purple category?  About tongue twisters?
Say these out loud:
"Fuzzy wuzzy was a bear.  Fuzzy wuzzy had no hair.  Fuzzy wuzzy wasn't fuzzy, was he?"
"Peter Piper picked a peck of pickled peppers."
"She sells seashells by the seashore."
"How much wood could a woodchuck chuck, if a woodchuck could chuck wood?"
