The trios needs to draw lots.

"How?" Paula asked.

"How about we draw on his face?" Sarah suggested

"That's so childish!" Jenny said.

"What if we pour cold water all over him?" Paula said.

Jenny whispered something to Paula and Paula nodded.

"Sarah, we have unanimously decided that you shall sleep on his bed and both of us shall sleep on yours!"

"That's not fair! Let's draw lots. Loser sleeps on his bed naked!"

Jenny tore up a paper into three equal portions. She wrote 'W', 'W' and 'L' on each of them and crushed them into paper balls.

"Whoever that draws the L sleeps with Andy fully naked!" Jenny said.
