Please answer the following question: Question: Who punches Lou? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Hot Tub Time Machine Context: In 2010, three friends are dissatisfied with their lives. Adam (John Cusack) has been dumped by yet another girlfriend, and his video-game-obsessed nephew Jacob (Clark Duke) lives in his basement. Lou (Rob Corddry) is a party guy way past his prime who is divorced and his family wants nothing to do with him. Lou has also failed in several investments and is debt-ridden as a result. Nick (Craig Robinson) has a dead-end job at a dog spa and a controlling wife named Courtney (Kellee Stewart) who is allegedly having an affair.Lou almost dies from carbon monoxide poisoning in what his friends think is a suicide attempt. Adam and Nick impulsively take him and Jacob to the site of some of their most memorable weekends, the Kodiak Valley Ski Resort, "where no one got carded and everyone got laid". However, upon arrival they see that Kodiak Valley has fallen on the same hard times as the four men. Upon arriving, they encounter Phil, a one-armed bellman (Crispin Glover). During a crazy night of drinking in a hot tub, they spill a can of an illegal Russian energy drink called "Chernobly" (named in reference to Chernobyl, Ukraine) on the hot tub's controls. The next day, they wake up in 1986. They can see each other as their 2010 age and appearances, but in their reflections and to other people, they appear as they did in 1986. Jacob, who has not even been born yet, somehow is still a full-grown man as he was in his 2010 state. They arrive during "Winterfest '86," the weekend when Poison played to a huge crowd at the then-thriving Kodiak Resort. At first, the guys do not think that they have traveled back in time but are convinced when they find out that Michael Jackson is still black, and discover that Phil, the bellman has both arms.It is a time that was hard on the group. Adam broke up with his first girlfriend and got stabbed in the eye with a fork. Adam's sister, Kelly, conceived Jacob with an unknown father. Lou was beaten up by Blaine, the ski patrol bully, and none of his friends came to his aid. Nick's show...
