Imagine walking with them and Dan/Phil (pick one. or both no judgement here lol) has their arm around you
oh goodness Dan you can't keep away from Phil for a few minutes. No wonder why you find Phil laughing at himself a lot. He's not laughing at himself he sees Dan laughing at what he said and it makes him laugh.
Amazing Phil / Phil Lester / danisnotonfire / Dan Howell/ dan got jealous
