Come On Rude Mug, Mug
There is nothing funnier than when you serve someone something to eat or drink in your home and they don’t realize there is a surprise hidden in there somewhere. If you were to serve someone tea in this mug and they didn’t know what was in there, it would be a really fun surprise.
If they were your family or close friends… it is probably best to keep this away from bosses and work colleagues if possible. It is all fun and games until you have to actually clean things. This mug would require a serious clean after each use and you would have a middle finger staring at you the whole time.
