There was this poor chap who was worried about being bald.
He took a felt tipped pen, and drew rabbits all over his head....................
Because, from a distance, they looked like hares (hairs) !
Then there was the other man who felt that he had a lettuce growing in his ear. The doctor wasn't convinced, but took a look and on seeing a small green thing, had to admit that it was the tip of the iceberg.
Another chap was doing jigsaw puzzles as part of his therapy. He was stumped by one particular puzzle. He phoned his doctor to ask for some help. The doctor asked him to provide a bit more information. The man said "well, the picture on the box is of a large cockerel" The doctor replied, "Clive, just give up, they are cornflakes"
