"show tables not like" in mysql

I was looking for the tables in my database not starting with "p_".  MySQL doesn't let you execute this command:

show tables not like "p_%";

Which is odd considering it will allow "like" here:

show tables like "p_%";

Instead, you have to use the information schema like this:

SELECT table_name FROM information_schema.tables WHERE table_schema = 'mydb' AND table_name NOT LIKE 'p_%';
