When sleeping during the night if a guy has an overly intelligent girlfriend it is possible to steal a few brain cells from his girlfriend if their heads are touching each other in just the right way. She will wake up just as intelligent because she has an endless supply of brain cells however the guy will wake up feeling smarter every time. It also helps the transfer if the guy is holding on to her almost like he is trapping her in his arms.
"I feel smarter today. I think that brain cell transfer worked."
