This isn't a major thing, but oh well...
In the Country Time Lemonade commercial when they're showing how relaxing summer is, the wind is doing two funky things. When the twins are in the flower patch, the flowers are blowing in the wind, but their hair is perfectly still. On the contrast, when the two kids are walking on the stone wall, their shirts are blowing (a whole lot, as a matter of fact), but the grass nearby and trees in the background aren't moving at all.
