"Hail to the bop believe me,
Took your time and come back and see me,
I've been waiting here so long,
and now you've taken off again."
If Hale-Bopp survives it's trip around the sun without melting it won't be back until around the year 4588, by that time I'm fairly certain you, me and Django Django will all be kicking up daisies (or whatever flowers are around then). Maybe we'll have colonised the moon? The last time comet Hale-Bopp visited we hadn't even built Stonehenge. Amazing.
