Would they need to use OSHA-approved rope?
Just continuing the original joke. Honestly, you can't write jokes that are as funny as reality is sometimes.
There is an Army Field Manual on executions. In making a scaffold, selecting a rope and tying a noose, you have to considered the weight of the condemned convict. Too much of a drop and you may pull his head off (messy), too little, he will be slowly affixiated rather than dying quickly of a broken neck. The coughing and sputtering can be uncomfortable for the executioners and the witnesses. An exceptionally heavy convict may require a stronger rope and beam. Leave nothing to chance.
