I definitely could tickle him, as I've been tickling guys for 50 years. However:
1. I'm not a professional tickler.
2. I have other things I would want to be known for in media, rather than primarily as a tickler.
3. I've now seen two videos about their "Tickle Tuesdays." In both of them, they don't look particularly cheery, which makes me wonder if the tickle aspect of this is not just exploitation for cheap, quick ratings. They don't seem excited about the whole thing.
