Cover art for Till My Head Falls Off lyrics by They Might Be Giants

personally, i think David Grimmer is on the right path, but i dont think its about old age in particular. i think the person described is a guy with simply many mental issues. he's obsesive compulsive (counting the advil), overly paranoid (why do you suspiciously), short term memory loss (someone more forgetful than yourself), afraid of speaking in front of large crowds, ect... this song i dobut is about any one thing in particular, seeing as how most of their songs are nonsense.
