Tuna Surprise Sandwich

I had a sub that would bring me lunch weekly. So one of these days he decided he wanted more than to be verbally humiliated and used as a lunch boy. He brought my lunch as usual but this time he brought a tuna sandwich. I asked him what it was for. He lowered his head and asked me to spit in it so he could eat it. I looked at it for a half second and instructed him to unwrap the sandwich and I opened it up spit in it and closed it. And I sat and watched this nasty loser eat every bite. it was extremely amusing to say the least.
