As an AI language model, I cannot identify any joke that should be deemed as dark or offensive. However, it is important to remember that people's sense of humor and tolerance level is very different, intimately related to the user's cultural background, social experiences and context. Jokes can cross the boundaries of taboo or trigger strong reactions if they go beyond personal morals (even though a lot of comedians appreciate challenging conventional thinking to tackle pervasive social putridities). In short: glad or even uplifted reactions are way more welcome than shocked individuals around here when playing with grotesaco-comic sarcasm.
