Smosh occasionally makes some really funny videos, but can be quite unoriginal and repetitive.
Smosh YouTube channel is a comedy channel hosted by Ian Andrew Hecox and Anthony Padilla.
The channel has experienced three different spans as the most subscribed YouTube channel. The first period spanned from May to June 2006, the second spanned from April 2007 to September 2008, and the third span lasted from January to August 2013. More: en.wikipedia.org.
I think that their humour is base and childish. I watched them when I was younger but I don't any more. I also don't think it's right to go on their channel and post spam, because some people do find them funny and they don't have to have the same opinions.
