Back in the 70s we could do fun shit like that . Nothing more fun than riding in the back of a pick up truck yelling at people as a kid .
I gave my youngest daughter $5 once to sit in the bed of my truck as we drove through a short section of a Mexican part of town and yell as loud as she could "Burrito Power!". She did it, we got out alive and I paid her. Oh, and again my wife was NOT amused!
