Heavy Lifting

I have this Marvin coffee cup I use at work that holds an incredible amount of coffee. Like 3-4 regular coffee cups. When it's full, it's incredibly heavy. Holding it by the handle is almost not possible and I frequently use a second hand underneath if I'm going from the Caribou upstairs to my cube.

Yesterday I switched to a smaller cup for a while. I reached to pick it up while looking at the computer and came very close to simply throwing it across the room. Coffee has made me strong.
