Look at script_lines.character_id == characters.id AND script_lines.episode_id == episodes.id which gives us the title and original_air_date

Query multiple tables (episodes, characters) - Find when the character moe szyslak first appears.

Part 2

Refactor our SQL to use JOINS

 SELECT * FROM `script_lines`, `characters`, `episodes`
	WHERE `characters`.`name` = 'moe szyslak'
	AND `characters`.`id` = `script_lines`.`character_id`
	AND `script_lines`.`episode_id` = `episodes`.`id`
	ORDER BY `episodes`.`original_air_date`
	LIMIT 1;
