- "I train best. I am Lugash."
Lugash is a gymnastics instructor. He has a thick Romanian accent and a large, brown curled mustache.
His origin is a bit mysterious as he says that he came into the United States in 1983 by cartwheeling over the Berlin Wall. However, another person claims that he defected into East Germany.
 Training techniques
His harsh but effective training techniques helped Lisa to achieve a high standard of gymnastic ability. He also has a habit of confiscating his students' cats and dogs, only giving them back when the student has accomplished a physical task. Once however, he refused to give back a girl's dog, but gave her someone else's cat instead.
 Anger management
He goes to anger management classes and threatens to spit on them.
 Behind the Laughter
- He is based on former U.S. gymnastics coach Béla Károlyi, who has his own gym.
- Apparently, he thinks that Lisa (who is only eight), is a "grandma". This is probably a joke poking fun at the stereotype of eastern European countries beginning to train potential future Olympic gymnasts at a very young age.
