What is an easy way to level up your gags on toontown?

Best way to train gags is in cog buildings, because there are plenty of cogs to train gags with. Best with invasion because double points. ( for example if you use a lvl 5 gag when in 5th floor you will normally get 15 points but instead you get 30 which is a good thing. )

Note : Too bad toontown cant extend the points more than 200 points because thats the max points you can go up to.
