How to tie a tie

I watched a video on how to tie a tie not because that interests me but because I have three brothers and half the time they can't tie their own tie so they come to me for help. But I mayself don't know how to tie one either. So I thought it would be best if one of us learned how. Now after I watched the video about five times I finally got it. It's not that easy to tie a tie I realized. However this video did help me so check it out!
