In "Betsy Ross Flies Her Freak Flag": 1. The sign to the Magical Farm Place Farm has hazy smoke around it, and all of the solders, including the one guy who introduces the Time Squad to Betsy who indiscriminately looks like Shaggy from Scooby Doo- has very pink rimmed eyes.
2. Betsy Ross gives Washington a plate of homemade brownies, but they were all eaten by Tuddrussel. Because of the fact that Betsy and everyone else has pink eyes and a chilled out disposition, and they all live in a smoky hippie commune, one could assume that Tuddrussel just ate an entire batch of pot brownies!
