I just saw a Carl's Jr. Huevos Ranchero Breakfast Burrito commercial that shows the US-Mexico Border. There are hundreds of cars waiting to cross into the US and lo and behold they show a SMB with a large roof rack and ladder on the passenger side.
They show the SMB twice. It is hard to make out the color since it is intentionally shot with a low quality look.
See if it is yours. You can go to their website but it is only an abbreviated version showing the SMB once: http://www.carlsjr.com/ontv/
In the lower left corner you may need to click "click for more spots" until you see the one titled "Border".
If it's yours you should get paid for your SMBs appearance...or at least get free food.
