Looking at the Burp Master Keychain that we featured a couple of days ago, here’s something that others might find more disgusting – the Fartmaster Keychain. Well, it works on the same principle with a trio batteries powering some realistic sounding farts sans the awful smell. Of course, you can always augment the effectiveness of this device and cement your position as the resident court jester by carrying a can of fart spray to use in tandem with the Fartmaster Keychain. Retailing for $9.98 a pop, you will be able to “inflict” the others in your vicinity with a wide range of realistic, side-splitting fart noises. A great way to excuse yourself from a particularly bad date, don’t you think?
