 Did you know air guitar strings are something you can actually purchase? At Stupidiotic, you can buy “easy to install” and “long lasting” strings that give your air guitar “that bright, airy sound you have always been looking for.” They can be yours for $2:00.

 
Take this as a disclaimer: We have no idea what you’ll actually receive if you buy these. Judging by the picture next to the product’s description, it looks like you’ll get an empty plastic bag.
