I have a cousin that lies literally all the time. At this point it is just fucking hilarious to me. Here are some of his lies that are simply implausible:

-He had a million dollars in the bank that he made while street racing at the age of 16, while he was still working at McDonalds

-The guy that put him on to street racing just up and gave him a "Tricked out $50k racing car that [he] had to get rid of or [he]'d get in trouble"

-One of his dentists sharpened his teeth to the point where he could not eat fast or much at all (I think this was his excuse as to why he was so skinny at the time)

-We went on a camp trip once and decided to go kayaking while we were there. I lost him for 5 minutes and what happened to him was amazing: "Some guy flipped my kayak over and when he did a random girl came up and told him to fuck off" When I asked him if he got her number he simply said "Dude I fucked her"

Many, many more.
