ELI5: Could planes benefit from having dimples like golf balls?

I watched the Vox video about golf ball dimples and cores and it made me wonder; could airplanes use the same dimple concept to increase stability? or do they already and i just never noticed?

No. Dimples help on golf balls because they help with base drag, that is drag created by the low pressure region behind the moving thing. However, the dimples increase drag from skin friction. Golf balls are not aerodynamic and thus have a lot of base drag, thus the dimples help. But airplanes are made very aerodynamic and have relatively more skin friction drag, so the benefit from dimpling the skin would be negated by the increased drag of skin friction.
