i just watched an episode in which he calls himself ricardo ricardo y acha which must be correct because enrique means henry not ricky i e rick richard ricardo in spanish not sure if there is an episode in which he calls himself enrique but although it kind of sounds like ricky it's an entirely different name so i doubt desi arnaz would have allowed such an error to be made in the episode in hollywood in which ricky forgets their anniversary date he very clearly says ricardo which makes his name ricardo ricardo he also says y acha or spelled y hacha not y de but he may have been contracting it
