There is no cake?

I had this sensation for a while. Since I left home this morning. I went to the groceries and kept realizing a nice but a little cold feeling. I am 88 years old now and I'm still in my right mind. But today...

...it seems as if my left arm has become an amalgamation of flesh and machine - a cybernetic device but with what purpose?

I focused all my attention on trying to move the arm, or at least the fingers, but it seemed that my brain was not in control here. Then I used my right hand to try and find hidden buttons, feeling up and down the surface of my left arm. Nothing. Suddenly, a door opened.

-How do you like your new upgrade?- said Dr. Dunklin strolling in with an arrogant smirk. -Nearly as much as I'm enjoying your stinking breath from here- He didn't reply to the cheap insult, still smirking he grabbed a pair of rubber gloves from his coat pocket.

With a stretch and a pop he was fully gloved up. Then he grabbed the pastry bag and intricately decorated the cake. He put on the last finishing touch, smiled, and turned it towards Dunkin. In a fine script it read: “Cat Puke Meow”. Dunkin sputtered with confusion, his face red.
