When Carol comes back to the hotel room from dinner with Melvin, Simon is changing into his pajamas. She helps get his shirt off in a very quick, harsh manner, then asks if he needs help with his pants. He says no. Scene goes back to Carol, then back to Simon. Miraculously, his black pants are now replaced with blue pajama pants when he couldn't even get the black ones unbuttoned. Wow, that was a quick change!!
