primary school teacher, who happened to be a stammerer, wanted to teach his class-three pupils the names of some water-loving animals. He wrote: Crocodile and Hippopotamus on the black board.
"N-n-n-ow re-re-pe-pe-peat af-af-aft-t-ter me" Then he said "cro-roc-roc-co-co-dile"
"Cro-roc-roc-co-co-dile" the class intoned after him.
"N-n-no, d-d-don't s-a-y it, it, it li-li-like th-th-that" he protested.
But after three unsuccessful trials, he abandoned it and proceeded.
"Hip-hip-hip..." he began, but before he could finish, the pupils all shouted in unison "Hurray" and ran out of the class, thinking it was the end of school day!
