calling "shotgun" adds 5 seconds to the blitz count. The second, and more common, rush QB rule is Mississippi rush (a blitz count), so called because the blitzing player must insert the word "Mississippi" between numbers so as not to allow the player to count ridiculously fast and effectively give the quarterback no time to throw (A common alternate to "Mississippi" is "apple". The word "Banana" is typically used by NAFs. In Canada the word "steamboat" is generally used instead of Mississippi). Sometimes the two rules are combined, allowing one separate call of "Blitz!" per set of 4 downs. The other option to handle a rush is to use an offensive lineman or center to block any pass rush. A line is rare in street, and the act of a center snapping to a quarterback is completely optional and nearly impossible in 2 on 2. When a center is used, the center is eligible as a receiver. Also the center sneak, wherein the center snaps the ball touching the QB hands but retaining possession and then running is completely legal and honorable in sandlot ball. Most teams that use a line opt for 3 down linemen(1 center and 2 guards). Some organizations that don't require the center to snap the ball to the quarterback only use 2 linemen. Popular plays include going long, the hook, the hook and go, and the down and out. A well practiced pump fake by the QB often accompanies the hook and go. Conversions after a TD usually are not applied and they can only be attempted from the 6 (or occasionally 7) point TD system, but if they are, there are several conversion systems, including "single point," "pass-run," yardage and "runback." The single-point is the simplest of the rules, in which any successful conversion is worth one point. Pass run is used in some midget leagues and awards 2 points for a pass and one point for a run. Usually all pass-run conversions are attempted from the 1- or 2-yard line. The second conversion system is the yardage system, similar to that used in the XFL playoffs, the Lingerie Football League, and the Stars Football League. The yardage system is formatted like this: 1-point conversions are attempted from the 1- or 5-yard line, and 2-point conversions are attempted from the 2- or 10-yard line. The runback is the most rare of the conversion rules,
