Little Johnny is always late for school and his teacher Miss Marple is getting sick and tired of his tardiness.
After another day of arriving late she warns Little Johnny that next time he is late he had better have a good excuse or she would take him to see the principal.
Of course a couple of days later Little Johnny is late for school once again and when he finally does turn up Miss Marple says to him
"Well Little Johnny I warned you last time you were late you had better have a good excuse, and what was it ??"
Little Johnny replies "well Miss Dad got burned today"
Miss Marple surprised by a good excuse asks "Thats terrible Little Johnny, did he get burned badly?"
To which Little Johnny replies "well Miss they don't fuck around at the crematorium do they"
