If the witch flies close enough to the radar dish to cook the kid, wouldn’t she be cooked as well? Or would that be another example of “cartoon physics”? :) Perhaps the witch doesn’t have any water? (Microwave ovens heat food by emitting microwave radiation that’s absorbed by the water in the food. No water, no heating.) Having no water would be consistent with how water causes The Wicked Witch of the West in “The Wizard of Oz” to melt. (Having something in or on your body that can cause potentially fatal damage is probably not a good idea.) (Yes, I’m overthinking this.)
Per Wikipedia, the U.S. flag had 15 stripes from 1795 to 1818. (This includes the famous “Star Spangled Banner”.) In 1818, Congress passed a bill saying the flag would have 13 stripes (to honor the 13 original colonies), and would add a star for every new state.
I believe PoodleGroomer is referring to the disembodied hand in The Addams Family TV and movie series, not The Fantastic Four character.
