Ear
Little Johnny was in a spelling bee in class. He had to spell the word and use it in a sentence. The teacher asked him to please spell the word EAR. Little Johnny stood up and proudly said EAR E,A,R. Then to use it in a sentence he pretended to take a big hit off a joint and then while pretending to have his lungs full of smoke he predended to pass the joint to little Suzy and said "Ear"
