Is bill kaulitz allergic to anything?

Oh, dude, is Bill Kaulitz allergic to anything? Well, like, technically, I don't have his medical records on hand, but, you know, people can be allergic to all sorts of things, like peanuts, pollen, or even bad jokes. So, like, who knows, maybe Bill carries an EpiPen just in case someone tells him a really lame pun.
