When Batman sings the world weeps

This was supposed to be a completely different comic. But sadly, my dinosaur drawing skills are simply not up to snuff. I wanted to draw a dinosaur in a shower cap singing Foreigner's sweeping ballad of love and longing, "I Want To Know What Love Is." I failed. I couldn't get the shower cap right and the dinosaur's body looked warped and sickly, which is just a real bummer. So I thought, 'Hey, how could this idea be 100 times more awesome?' The answer was simple. Batman. Of course Batman would sing the classic hits of the greatest British/American rock bands of the 70s and 80s. Admit it, who would not want to smash their face against the face of someone hot when listening to this sweet-ass tune? 

And it goes without saying that Batman has excellent musical tastes. That he sings in the bathroom, using his purple toothbrush as a microphone while wrapped in a pink towel. It's also understood that he wears his bat-mask at all times, even in the shower. Mostly because putting that black eyeshadow around his eyes is a real bitch. Who would want to do that several times a day? He'd go through a tub of Vaseline in a week (this comment will only make sense to women who remove their eye make-up with Vaseline, which is not recommended by dermatologists as it can cause irration to the eye and requires no small amount of pulling and tugging on delicate eye skin that can lead to wrinkles). So yes, Batman sings Foreigner songs while he gets ready. After this rendition, I can only hope that he went on to sing "Hot Blooded" or "Dirty White Boy." But part of me knows that he sticks to the syrupy love ballads so he probably went with "Waiting for a Girl Like You." 


Question is: what kind of jam would Robin sing in the shower? D'Angelo's "Untitled (How Does it Feel)" or Blackstreet's "No Diggity"? The world may never know. Or will it?
