$a = "select * from jokes where id = \"$joke\"";
$b = mysql_query($a) or die(mysql_error());
$c = mysql_fetch_array($b);

I got a headache reading the text, but this query string in your htaccess is missing the second parameter and ampersand:

/view.php?joke=$1=$2

Code (markup):

should be

/view.php?joke=$1&param=$2

Code (markup):

 

Indeed.

I also saw you made quite a big mistake; your code is easily "hackable" with an sql injection. To prevent this, do the following.
FIND:

$a = "select * from jokes where id = \"$joke\"";

Code (markup):

ADD, BEFORE: (on a new line, before the previous line)

$joke = htmlspecialchars(addslashes($HTTP_GET_VARS['joke']));

Code (markup):

If you don't do this, it's very easy to hack your database and such. Very dangerous thing, sql injection

 

I don't think the htmlspecialchars() should be used here : you don't need it for the database (which doesn't understand HTML), it'll just make the stored string longer and make it cumbersome to use it for anything else than HTML (what if you want to output it in a plain text file or some email ?).

IMHO htmlspecialchars should be used when displaying the value after pulling it out from the database, it makes more sense that way.
