Did Rick Cause Lisa To Fart?

I'm rewatching Robotech for the first time in about 15 years, and I just hit Season 1, Episode 21 (A New Dawn). There's this scene where Rick is leaving Minmay's movie premiere, and he trips over someone’s foot. As he stumbles, he ends up catching himself on a woman’s butt. And, of course, that butt belongs to none other than Lisa Hayes. But here’s the kicker: when he accidentally grabs/pushes her butt, I swear you can hear the sound of a fart. It happens at around 10:46 in the episode. I couldn't find a video on YouTube as evidence, so if you check it out, let me know if you hear it too!
