The Logan Effect

It is when you plan on watching only one video on the internet but end up watching more than one.

Friend 1: Dude, watch "I Just Had Sex" by The Lonely Island ft Akon
Friend 2: A'ight
Friend 1: Did you watch it?
Friend 2: Yeah I did, The Lonely Island are life...now I'm re watching all of their stuff.
Friend 1: Ah, The Logan Effect
Friend 2: Now you just making stuff up
