Get the grumbach mug.
A true gentleman and a distinguished worker. If you meet someone with the last name Grumbach, they will definitely help you when you are feeling down. German origin relates to a creek or steady flow of water. A Grumbach can be wild, but his/her support and consistency flow steadily like a stream.
That Grumbach kid is kinda strange, but I'd trust him with my life.
