The mascot of the band "The Wonder Years". There's some meaning to Hank in the lyrics of the song "My Life as a Pigeon" from their album titled "Suburbia I've Given You All and Now I'm Nothing":
"I guess this is what it's like
The life of a pigeon
I know we're hard-pressed to find some common ground
But I won't let this world wipe me out"
Pigeons are known as annoying, good-for-nothing birds by a lot of people. The main meaning behind Hank the Pigeon is that you should keep on pulling your weight in the world even if people try to knock you down.
Jenna: What's up with The Wonder Years and the whole pigeon thing?
Tay: That's Hank the Pigeon, and it's basically their mascot, but it actually has meaning behind it.
