"Jackass" Parody, any suggestions for stunts?

Hi. Me and my friends are making a "Jackass"-type movie, and we were wondering if anyone had any ideas for any stunts/pranks that we could do? Please nothing that would get us seriously injured or arrested XD.

Go into walmart, into a changing room and start yelling, "there's no toilet paper in here!" bring something smelly with you in a zip lock bag so you don't get anything on their floor, and not get charged for damages.
