Just curious. The State Constitution in Article V §2 states: "The lieutenant governor shall perform such duties as may be provided by law." As far as I know, the only direct duty is to approve name-change petitions. Are there any others besides serving in the absence of the Governor?

Sounds like the perfect job for someone with the personality of Wally from the Dilbert strip. Low stress, fairly good pay, and you don't really have much to do.
