Going by the comments over at gocomics.com/overthehedge there seems to be a lot confusion about today’s cartoon. So I’m going to go all Gilbert Gottfried on you and explain the joke (clean joke, Gilbert only explains dirty jokes (see YouTube video of Gilbert at George Takai’s Friers Roast (NSFW)).
Wax beans are just yellow green beans. Not yellow-green beans. But green beans that are yellow.
The original rhyme goes, “I scream, you scream, we all scream for ICE CREAM.” Ice cream is way better than organic wax beans.
Get it? Good.
