The meme might be found funny because it plays with the double meaning of the word 'information' as both biological data and as a term commonly used in the context of digital data transfer. The final statement 'That's a lot of information to swallow' is a punchline that refers both to the conceptual 'amount' of data and a colloquial expression that can have a more adult innuendo. The humor arises from this clever wordplay and unexpected juxtaposition of scientific fact with a colloquial phrase.
