The Grindhouse star left a tray of the baked goodies out for the salespeople and potential buyers, not realising they were 'edibles' her aide had made for her to try.
McGowan says, "There were eight realtors and inspectors coming to the house... and you have to get out of your house... and I notice there's a big, huge plate of brownies that said 'Enjoy!' on the surround-wrap... and I just left, I didn't think about it.
"At 4.30 that afternoon, I get a call from my realtor saying, 'Erm, I'm at my parent teacher conference; was there anything in those brownies?'
"I'm imagining all these poor people... high as a kite, like, 'What the hell happened in Hollywood?'"
