My kids found the funniest web site. They love playing funny games and this one is one that even I got into. It is called Ski Battles. Basically, you build a ski slope, push play and watch a little man on skis slide down (or fall down) the slope you made. My kids love to put bumps and strange obstacles in the way of the skiier and watch him fall. It is funny and really quite challenging to make a good slope. It is on a site called addicting games and with ski battle, it is addicting!
Give it a try.
