Table trouble

I'm setting up a table in MYSQL and I get an error at the closing bracket. I followed the text book and I don't understand why or how to fix it. I'll include my code. Thanks in advance for your help.

mysql> CREATE TABLE joke (
-> joke_id MEDIUMINT(5) DEFAULT '0' NOT NULL AUTO_INCREMENT,
-> joke_question MEDIUMTEXT NOT NULL,
-> joke_answer MEDIUMTEXT NOT NULL,
-> joke_date DATE,
-> PRIMARY KEY (joke_id),
-> );
ERROR 1064: You have an error in your SQL syntax near ')' at line 7
mysql>

Remove the comma after "PRIMARY KEY (joke_id)"
