No, you'll have twenty entries in the 'hobbies' table. The middle table 
- the lookup table - will have up to twenty rows per user - however many 
hobbies they chose from your form - times however many users.

And with the lookup table just having two key fields in it, you can jam 
a lot of data into that table without it stumbling. Far far more than 
up-to-20 * hundreds. :D
