In the immortal words of Brian Wilson: "I'm gonna be round my vegetables, I'm gonna chow down my vegetables, I love you most of all... my favorite vegetable"

And he's right, too. 

In this episode we get down in the dirt with our favorite veggies. Carrots... broccoli... and all the rest. All that, and Ceri tries out a fun new pun!

If you look out a window right now, you're probably going to see a tree. And that tree? Why, it's made out of wood, friend. And that's where things start to get interesting... 

Get ready to meet Hank's newest alter-ego: Mr. Wood. He's basically Hank, but he just can't stop talking about wood! I had to cut like 3 different, very long stories he told about wood! The man LOVES wood!

Monster Month meets its ghoulish end, and we’re throwing it a swinging wake! This week, all the monsters we didn’t talk about during the rest of October come together for a great big Monster Mash!

Halloween is my favorite time of year, and this one has been more than a little weird. But working on Monster Month helped make up for some of the creepy fun I'm missing out on, and I hope it did the same for you!

RIP Monster Month! For now...
