I can do my weekly routine, the other hemisphere wakes up to a nice clean dive, cool!<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">But there are some issues. One hemisphere is awake, gets mama in the mood, later the other hemisphere wakes up and finds out he missed out while he was asleep, he’s pissed at the other hemisphere, they get to fighting over her, later that day he wants some of what the other side got, the boys downstairs are calling for mercy.
