In an Idiots first, the guys take on a three part episode, covering a very breviated history of wolves becoming dogs, then how different breeds came about, going into breeds that have gone extinct over the years or were rolled into other breeds, and then concluding with a discussion about bringing one breed, the French Bulldog, away from the brink of extinction.
In what many are calling the greatest trilogy of all time, better than the Lort of Da Rings, Star Warz, Goodfadder, and Alans, the Idiots bring their journey to an end. In this, they discuss French Bulldogs, who were thiiiiiiissssss close to being extinct, and how some lady I'm too lazy to go back and listen or look up saved them. She's a hero, though. They talk again about selective breeding, and how even foxes have been bred to be closer to dogs, and slowly develop floppy ears in place of their pointy ears.
Also, seriously, go look up rose eared Frenchies. Seriously, go. You're welcome.
