"Fuck, what a DAY!" Harv stormed into his house, threw his coat and briefcase across the living room, ripped open his shirt and plopped down at the table.
"Now, dear, relax."
"Fucking wife always telling me to relax," he thought to himself. "Why i oughta—"
Harv was sick and tired of being in his body. Nothing but stress and pain and a stupid wife. He went into his room, opened his closet and took out a shoebox-sized vault.
He opened it, extracted a human brain and held it in his right hand. He then flipped open his cranium, grabbed his brain with his left hand. He positioned the new brain directly above his cranial cavity, and yanked out his old brain. As his body went limp, his right hand opened and the brain plopped into position.
Bert sighed with relief. "Harv musta been having one of those days..." He placed Harv in the vault, and closed his head.
