Using voice commands with Alexa and RTM is cumbersome, and one of the big reasons is that saying "Remember the Milk" is a mouthful. Shortening it to "RTM" is good, but a bit esoteric. So why not make it more memorable by naming the cow "Artie" (i.e. the RT from RTM). Then people can just say, "Hey Alexa, tell Artie to remind me to xyz at five-thirty."
