Grenades are awesome because you can lob them at people you hate and blow them up. If you’re not that big on making people explode, then you can alternatively turn grenades into cool looking car parts! I’d suggest the latter.
Now, it’s important to understand the difference between a dummy grenade and a live one before performing any of the above tasks. This Pineapple Grenade Gear Knob is a dummy, and is definitely going to increase your cars standing on the Badass-o-meter. Not only will it receive tons of compliments & attention, but may even prevent a few car thefts too!
