Get a Gerde mug for your dad José.
The substitute who you never know if he will tend to your class. Has a styrofoam cup filled with who knows what. Likes telling stories with absolutely no relation to class. These include stories about: his cats, salt, his cats, his cats, and other things. He has a sac on his neck. I assume its filled with stories or mabye it opens up and unleashes a fiery inferno when he is mad.
