Yeah, but I was amazed at how blatantly he lies in it. He says stuff like (paraphrasing here) "they were going to have the rabbit ask, what's cookin', and I asked if he could say "what's up doc" instead." This goes against what Tex Avery and others have said about it-- that it was a very common phrase back where Tex grew up, and he decided to use it.
He also takes the credit for coming up with the name of the character, even when historical evidence shows that it came from a model sheet labelled "Bugs' Bunny", referring to the Ben "Bugs" Hardaway, director of 'Porky's Hare Hunt'.
I know that some other Looney Tunes-related people stretched the truth to gain recognition back in the 60's and 70's, such as Bob Clampett, but I don't think he ever told any really concrete lies like the above-- with him it was more like "I helped Tex a bit on A Wild Hare and gave him some ideas" rather than "I singlehandedly came up with the character's name and catchphrase."
He also tells stories about how he came up with Porky Pig's stutter (the story's a bit nonsensical because he says the stutter came from a gruff 'grunting' voice he thought a real pig would have, and then he segues into the Porky voice, which is completely different). He wasn't even the one who originated the role of Porky-- he replaced someone else, who I believe stuttered naturally (which is why they replaced him-- it took him too long to say every line, eating up precious cartoon time).
