Mom,
I answer to your question... you can always find any funny video that is sent to you on Youtube. I would suggest just posting a link to the youtube page. To post videos as html is is a bit more complicated. There is also a forum plugin for youtube (not sure if you can use it here) that will post the actual video in forums.
Here are the links to the youtube version of the videos you sent me.
