More like...um...SKUNKle Grandpa! Yeah, that's the ticket!

At the risk of being that guy, I'm pretty confident I'm not imagining this one...well, moderately confident.

 

Yes, it's established in the previous and subsequent shots that's a palm tree air freshener, but that's certainly now how this shot's cropped. This is bolder than a split-second of someone, say, running past 'Room 420' - I like it. Let's review what else we see in this frame - the robot's eyes are red, the mirror just got blasted, and the only other thing we see in the mirror is Uncle Grandpa's hand raised as if waving. Waving. As in "hi!". Not to mention the fact that the trucker is surprisingly nonchalant about the goings-on.

Unfortunately, I can't say for sure that my cartoon-addled brain wasn't just adding its own funny part there - the episode this appears in, "Perfect Kid", was otherwise the weakest of the series so far. Thoughts on it and "Big in Japan" coming soon.
