The article claims, “Additionally, it is believed that hiccups originally come from an adaptation of amphibious humans so that the glottis would close forcing water out of the gills similar to a frogs croak or ribbit.” Amphibious humans? With gills? My first reaction is Who writes this Crap?! On second thought, could it be a myth told by the didgeridoo players? In any case it is not relevant to an article about producing speech; it might be relevant in the article on hiccups, which already discusses the evolution from amphibians. So I will delete the sentence. — Solo Owl (talk) 15:03, 9 January 2011 (UTC)
