There seems to be a lot of social media challenges circulating online lately. This one, though, looks to be fun and the least life-threatening of them all.
The "Not my legs" challenge is an extension of the "Not my arms challenge" where you grab a partner and use their limbs to tell a story. This boyfriend/girlfriend combo joined forces to tell a funny random story using each other's legs.
This duo is no stranger to YouTube. Their 'BFvsGF' channel is full of challenge videos as well as funny pranks they play on each other.
It is clear that laughter makes the heart grow fonder for this couple.
