I love pumpkin pie, but only really around this time of year. I can't see myself eating a pumpkin pie in May, for example. Same thing with eggnog. I'll drink the hell out of egg nog from November through December, but eggnog sounds gross any other time of the year.
The first comment on today's comic is someone saying whipped cream doesn't come in tubs and Cool Whip isn't whipped cream. Just shut the hell up, Robert!
