What is the best stealth smoking technique for my situation?

[Runaway Jim]

thats wat i do.
except the sitting part.

one time i leaned out my window, and saw a cop car just sitting there in the middle of the street, i froze, i was like "oh sh*t im busted", but after a minute he left.

I love when cops see me smokin bud in my house, because unless i am waving around 5 lbs of bud out the window while growing a plant, they cant do shit about it.
