mysql> SELECT JokeText FROM Jokes WHERE JokeText LIKE "%chicken%";
This query displays the text of all jokes that contain the word "chicken" in their JokeText column. The LIKE keyword tells MySQL that the named column must match the given pattern. In this case, the pattern we've used is "%chicken%". The % signs here indicate that the word "chicken" may be preceded and/or followed by any string of text.

I suppose we should both open our eyes wider ;)
