For those of you who continue to whine about Baa-sama and Jii-sama apparently not doin' da dirty, consider that they both remember throwing out their backs the last time they tried, and neither one wants to push their luck quite yet...
...Or, maybe they're thinking that doing two-person push-ups would undo the spell, returning them to their mid-80s, and they're not ready for that quite yet...
...Or, it could be that since "public displays of affection" were frowned upon for so much of their lives that they can't bring themselves to do it now - and that, behind closed doors, the neighborhood rabbits can't keep up with 'em, if you know what I mean...
