I always get a kick out of XKCD comics and the latest one does not disappoint. They take on the US cell phone number this time along with area codes. This is all because US cellular carriers stopped caring what your area code is when roaming charges and national long distance went away. Remember those days?
BTW also worth checking out is XKCD’s visualization of the history of congress. I always find US history interesting with odd occurrences like Democrats being pro slavery.
