You heard me correctly.
It is bright yellow, with a large, smiling, yellow, square Spongebob head at the top. (Not, presumably, the bit that actually enters the ... err ... area in which a rectal thermometer typically enters.)
Don't believe me? I even found it at Amazon.
Charlie, of course, immediately started singing (to the tune of the Spongebob theme song) "Who lives in a brownhole behind where you pee? Spongebob! Squarepants!"
And then he bought it for my Dad for his birthday.
In a world where such a thing exists, is a Hello Kitty Assault Rifle really any more ... wrong?
You tell me, my friends. You tell me.
