Yep. As long as you're not lifting a leg and leaning (or rattling the windows), you should be able to crack a few off on a date no problem. I used to be able to tell you at a glance if a certain piece of furniture (say, for instance, a couch) was going to 'hold' one for you*, or if you'd soon be basking in your own glory.
It helps if you can time 'em with an excuse - say the waiter taking the order at the table next to you, passing a farm while driving, etc. You can sometimes blame the dog - but only if she hasn't experienced your dog's farts yet. (My lab has a very distinct "brand". Will water your freaking eyes.)
*I had an armchair in my dorm in college...thing was great. You could drop the nastiest, foulest, most unholy bomb known to man in that thing, and not smell it a bit. But god help the next poor sap to flop down in that chair - it'd release the last two weeks worth it had been holding. You always GENTLY sat down in that thing. Every time we had women coming over, that thing got a full BOTTLE of Febreeze.
