The first new Dr. Seuss book in 25 years, Which Pet Should I Get?, was released Tuesday to promptly sell out on Amazon. Late-night TV host Jimmy Kimmel could have easily read an excerpt. But instead he enlisted Tyler, the Creator to rap it—and apparently, that isn't as easy as it seems. The Odd Future ringleader looks great in his Cat in a Hat suit, though he struggles to find his rhythm as he reads Seuss's rhymes. Once he does, though, Tyler goes ahead and adds an aside: "Jimmy Kimmel, this segment was wack." Sadly, we must agree. Tyler's instincts to add more "Matthew McConaughey" were on point, and it's a shame Kimmel rejected the idea. Watch below.
