Dont know i f this counts - but my buddy and me were dating these 2 chicks.... but then as it went on we realised it was the same chick - she was dating us both...and she didnt know we knew each other... then once we found out we kept dating her. Interesting how she was thinking she was having fun by dating 2 guys without us knowing and we we knew and decided to continue with her.... didnt last too long, a few weeks, and we both called it a day on the same night.
