I'm going to go against the grain here and say that I absolutely loved Frank Caliendo. While some other Yelpers may say his jokes are outdated and stale, I thought they were easy to relate to, and felt familiar. The husband was really big on seeing this show - I went along because hey, he sat through Lion King with me (which we both loved). I was so surprised. I loved all of it, the political jokes, the Bush/Clinton impression, Charles Barkley ... but what killed my Husband (who laughed so hard I thought he was going to have an aneurysm) was the Morgan Freeman bit. Hilarious!
That being said, I don't think this show is for the under 30-35 crowd. Just a bit young to remember/appreciate some of the older jokes.
