Jim Gaffigan is not offensive and really funny.
Michael Ian Black is very offensive and mildly amusing.
You're Not Doing It Right: Tales of Marriage, Sex, Death and Other Humiliations was hard for me. Black complains a lot about his children. I am SUPER sensitive about this because my dear, sweet, loving, kind and beautiful personal adviser and her husband lost their beautiful, sweet, incredible baby girl before she was born. And I feel like life is a sacred gift. And I feel like joking about how much you don't like your kids is never funny. And I am admit that this is a personal bias. And so right away I didn't like MIB.
Then I realized that he has written some children's picture books that I really like such as A Pig Parade is a Terrible Idea and The Purple Kangaroo.
I then found out he was on one of my most favorite shows from yesteryear, The State.
Still, this book is not funny. And I won't be reading another MIB book. Some jokes are just "too soon" for always.
