That's why I recommended checking out the acts online ahead of time. If you start to hear something you find offensive, it's easy to shut it down right there rather than walking out of a club during the skit (although those usually produce very funny moments from the comedian).
To see who is performing, about 1-2 weeks before the cruise, your cruise compass will start to populate. I knew the comedians on our last two Oasis cruises prior to sail date.
And yeah, I agree, OP will probably need to sit that one out...but still wanted to share how we do our intel on talent prior to boarding. We don't do it to get a temperature for vulgarity, but rather to see if we know them from other cruises or on tv somewhere.
Also for good clean comedy, check out Dry Bar Comedy online!
