Not very funny at all. It is a "hidden camera" type prank show, but the skits are not funny and feels very "fake", like the people who the prank is on ARE ACTORS themselves. In the pilot a prank is pulled on a man's wife where a stranger kisses the wife passionately while the husband looks on. First and foremost, if this was "real", no husband will stand by and allow it and second of all, the skit is not suitable for young viewers.
Another obvious thing is Howie Mandel is in disguise, usually just a wig, and particpates in the skits, but even with his disguise, he looks like HOWIE MANDEL!!! So it is obvious everyone are actors including the victims.
Anyway, there are a billion prank hidden camera shows that have come and gone and this one is by far the worst. It will not be around long.
Most of these pranks on this now-canceled show were stupid, but not all of them were inappropriate. However, quite a few of the pranks were inappropriate for younger kids. For example: one prank involved a pole-dancing video with elderly ladies, another involved a gangster cooking show called "Eat That B*****s", and one recurring inappropriate prank was "Desperate Housewives"-lite (the one MovieBuffman talked about). If you're looking for a family-friendly hidden camera show, skip "Howie" and try "Just for Laughs" on ABC.
