At first I thought they were talking about all the graffiti.

So much /c/badlinguistics in this thread.

Technically non-human animal communication isn’t language.

Edison didn’t do any damage to Tesla’s name (he was more than capable of doing that himself), and by all contemporary accounts the two men seem to have supported each other the brief time they were together and parted ways amicably. (Also, Edison personally had nothing to do with electrocuting Topsy the elephant - see 4:09:00.)

Oh boy! Another pizzacake to downvote!
