Hot Tub Time Machine (2010) ending / spoiler
Lou stands up to the ski patrol guy and takes from him the Russian energy drink needed for the hot tub to send him and his friends back to the present. Adam (John Cusack) says good-bye to April (Lizzy Caplan) and she tells him that they should meet again and that maybe "the universe will join us again some day." The energy drink is poured into the hot tub's controls and everyone except Lou goes back to the present. Back in 2010, everyone's life has changed: Nick is a successful music producer and his wife didn't cheat on him (because in the past he called his wife and told her to not cheat). Adam is happily married to April. Jacob now has a relationship with a father he never met (Lou). Phil (Crispin Glover) had his arm re-attached thanks to some help from the ski patrol guys. Lou is married to Kelly (Jacob's mother). He used his knowledge of the future and made lots of money by inventing Google (now called Lougle) and also by being the singer of Motley Crue (Motley Lue).
