My best friend and I had this conversation back in college when we'd smoke stuff other than cigarettes on a very regular (chronic) basis. We'd chief out a little bit and get into really heated races on the SNES version of Super Mario Kart. We started talking about time travel one time when we were particularly munted. We also always talked about how much we loved Super Mario Kart when we were kids, so we decided that if we had a time travelling device we'd get baked, go back in time, abduct our 8-year-old versions of ourselves and play video games with them all day!
