If you've ever had wasabi - that curiously strong green paste* in sushi - then you'd know it's weapon-grade food. But it's not every day that you hear it actually used as a weapon:
A Massachusetts college student is facing criminal charges after admitting he assaulted his girlfriend with a pair of jeans covered in wasabi sauce, an attack that the man claims was prompted when “some guy she slept with in school was texting her.” [...]
The woman doubled back to McGuinness’s home, where he “came out to the driveway with my jeans covered in wasabi sauce.” She told cops that McGuinness “had my jeans by the waist and whipped me in the face with them. I got wasabi sauce in my eyes and they were burning and I couldn’t see.”
*yes, actually just colored horseradish and mustard in most countries outside of Japan. REAL Wasabi is a bit different.

second, you CAN get wasabi in the US...but it tends to be pretty expensive (and it's true that most "wasabi" sold in stores is basically just horseradish dyed green.) i've had real wasabi a couple times, and as much as i like the "dry spicy heat" that horseradish provides, REAL wasabi is pretty brutal. i mean, it tastes good and is a good accompaniment for sushi/sashimi, but it's REALLY strong!
if horseradish clears your sinuses, real wasabi will make you feel like your entire head has been hollowed out!
