(Shutterstock) (Newser) – Did you know that wasabi sauce slathered on pants counts as a "dangerous weapon"? Or at least, it does if you shove it in your girlfriend's face, which is what 22-year-old John McGuinness allegedly did in the wee hours of Friday. The Cape Cod resident was angry with his girlfriend because she'd been texting another man, so he called her and told her he was about to throw out a pair of her jeans—a $200 pair of her jeans, the Cape Cod Times reports. The girlfriend rushed over, and found McGuinness outside holding the jeans, which he'd doused in wasabi sauce. He then allegedly forced down the window of her car and grabbed her cellphone. When she got out of the car to retrieve it, he shoved the jeans in her face, getting wasabi sauce in her eyes. Then he poured more of the spicy stuff into the car. Police eventually arrested him, and have charged him with, among other things, assault and battery with a dangerous weapon.
