I love these responses! I'm not too good at making up funnies, so let me just throw an FYI at you.
If you decide to replace your belts, here is a little tip for you. Ther are basically 2 common types of automotive V-belts on the market. They are commonly referred to as top cord and center cord belts. Some parts stores, like AutoZone only sell the cheaper center cord belts. Other chains like NAPA offer both grades for you to select from. Just like the name implies, top cord belts have the strength adding cords closer to the top of the belt where the belt is wider. This allows for more cords in the belt. More cords = stronger belt.
So, get yourself some good quality top cord belts and stop worrying. They easily last 2-3 time as long as the center cord belts and you will have fewer problems with stretching and slipage.
