A risky comparison

A condom and bungee jumping are exactly alike, if the rubber breaks, you're f**ked.

Explanation

Experiment

The joke makes a comparison between the failure of a condom and the failure of a bungee cord, both of which have potentially disastrous consequences. It plays on the shared risk of 'the rubber breaks' in both situations, which can lead to unwanted outcomes. The use of vulgar language adds to the shock and humor.
