There are many self-respecting ways to be toss away of after you give way , from cremation oraquamationto beingfired from a catapult at your enemies . However , for some inauspicious souls , being buried is n’t the last that will be seen of them , thanks to their casket exploding out their cognitive content .

In her " Ask a Mortician " YouTube series ,   funeral undertaker Caitlin Doughty explains that it happens when bodies are sealed a small too well into their final resting place .

" You really need adecomposing bodyto have approach to some variety of air so it can then desiccate . But if it ’s one of those passing sealed protective casket , there ’s really no place for all of that gas and fluid to go and so the consistency can kind of plough into sort of a peat bog . Like , tool from the Black Lagoonstyle . "

The gas pedal within the casket or mausoleum builds up , ineffective to run away until it explodes or cracks , spraying your mulch on the lid .

" If it ’s a violent enough of a blow , it can even dislodge the marble front of the crypt , " Doughty says in her video .

She then shows a pic she took of a front that had indeed been blown off in this direction .

A mussy end similar to thishappened to the first Norman king of England : William the   Conqueror . William sustain an injury while riding in conflict , which pierced his intestines . As he slowly died , the people in his living — most of whom he had not treated well , and his son , who he was at literal war with — resolve not to take on the matter of arranging his funeral . After he died , his body was give decompose on a stone slab while wait for someone to offer .

finally , a knight did take it upon himself , and ship the torso a full 112 kilometre ( 70 miles ) to Caen to be bury , as the body continue to break down . The mogul , no longer absorb with issue of dominion , now wiled away the minute by hoard gas through decay .

Upon arrival , a fire in the city warmed the corpse up some more and continue those gases expanding . By the day of the funeral , it was too bloated to fit into the sarcophagus . Undeterred by canonical physics , like a toddler adjudicate to jam a straight toy dog through a circle - shape hole , the gravediggers nevertheless seek to cram him in there anyway .

It was at this point that thebody blew , and “ the vain bowels burst , and an intolerable foetor assailed the anterior naris of the by - stander and the whole crowd ” . The mourner got covered in all in Martin Luther King juice .
