Simple card games

[sherrardk]

Been playing War with the 5 and 7 year old and they both get very excited when they win (obviously, they think it is down to their wonderful card-playing skills). Now, however, I am getting a bit bored of it, anyone know of any other simple card games that I could introduce (have played Patience with them but it takes ages to set up). Thanks (and yes, I expect there is a more suitable category for this question but couldn't think where to put it.)
