I realize this is a little late, but oh well.
In Chariots of the Dogs, when Sam and Max meet their past selves and the past selves go back into the time machine leaving present S&M to go through the past year and a half again, the past S&M take the recording contract with them, which is needed for the Present S&M to go through the past year and a half again. When the Future S&M get the Recording Contract from the Past S&M, the Past S&M go back to continue their lives. But to do that, Past S&M need the Recording Contract that Future S&M has. Also, Past S&M somehow know that they need to go to the moon, even though the Past S&M are from the events of Episode 2, and S&M don't learn that they have to go to the moon until the begining of Episode 6.
How is any of this possible! Could someone please explain?
