Here’s more juvenile humor for the masses that costs a mere $3.95 for plenty of laughs – the Pull My Finger Fart Pen. This writing instrument is pretty much self-explanatory, and it does look like a real digit, letting one rip whenever you give it a nice tug. I think this would be a hoot at the exam hall as stern invigilators go nuts wondering who had too many beans for breakfast that morning. It won’t give the game away that easily with multiple fart sounds, including both long and short ones. Heck you can even sign your John Hancock with this in blue if you want to.
