Graph Theory Joke

While registering for the Association of Computational Linguistics conference in Korea I came across this gem for a workshop.

TextGraphs is in its seventh edition! This shows that the disciplines graph theoretic models and computational linguistics, are naturally connected, with a large variety of Natural Language Processing (NLP) applications adopting efficient and elegant solutions from graph-theoretical framework.
There's a funny in there, but maybe just if you're a nerd in the right field.
