New XKCD Forums

Title text: There has long been debate about Big Bird's species, with some experts claiming he was a canary, but recent genetic analysis places him firmly in Cariamiformes.

Of course, if you did X-ray Big Bird, you would just see human bones.

Has Big Bird gotten x-rayed?

(Wondering if Sesame Street would do episodes on things like broken bones… it's a darker topic than what I usually associate them with, but on the other hand, broken bones are a thing kids sometimes have to deal with, either because they broke a bone or they know someone who has. I haven't seen the show recently enough to know whether that's the sort of thing they'd do.

On a third hand, x-ray is one of the few words that begins with X, so I could see them having characters x-rayed while talking about the letter X.)
