Cover art for Come Back To Bed lyrics by John Mayer

@ms abbey, I interpreted this as a double entendre, with the use of 'and' instead of 'point' between 98 and 6.
98.6 degrees being the temperature of the human body (physical); and 6 degrees of separation referring to people who have a connection but do not directly know each other (mental). At its most basic meaning he is pleading with her to close the physical and mental distance between them by coming back to bed and communicating directly to him what she is experiencing.
