Flopcast episode 490! The subject of today’s Top 4 ½ List is, uh, whistling. We’re still not sure why. But it’s a fun list, including a classic TV theme song, a Bangles song, a bizarre Boston clown, a Muppet, a Guardian of the Galaxy, and lots more whistling weirdness. (We somehow missed the Frosty the Snowman traffic cop who swallows his whistle. Oops.) And we assure you, this show contains no actual whistling, so you may proceed with confidence. Your dog won’t freak out. Also: National Drink Beer Day is this week! So go ahead and wet your whistle. Or your whistlepig. Your choice.
