Misi 4 GTA: San Andreas

Get Twice the Amount of Progress With Girlfriends
You have to have two controllers for this trick. When you go to your girlfriend's house you have a choice of either going on a two player free roam or going on a one player date. However, at the end of the one player date the two player icon (usually located by the door) will linger for a few seconds. You have to quickly go into the icon and activate it before it disappears. After that you can either end the free roam quickly or play around it doesn't matter. If your one player date was good and you gained progress you will gain even more progress from the free roam. However, if you had a bad date you lose more progress by activating it.

Infinite Spray Paint
In the earlier Sweet Mission "Tagging up Turf" you receive an infinite spray paint can. Since there is no timer on this mission, you can go around Los Santos with the FAQ tag map and spray all the tags without refilling the paint. Sweet!
