here's what i'd do.... i'd have them in your pocket... but ask him about 'em first... don't just bust 'em out.. be like..

dad what would you do/say if i was ever to pull out a j and offer to smoke with you...

if the answers sounds bad lol, don't pull 'em out..
if it's good, then do it.. but you also gotta listen for sincerity in his voice..

he could want you to pull 'em out to bust you or w/e.. but that's easily enough to tell.
