LOL Boo
But being serious
You could try this..
You can loosen it off the hairs of the coat with a little vegetable or sunflower oil brushed through the coat with a fine comb, but basically you either get some patience or you cut it out of the coat because it will take time to groom out naturally.
Or,
Being oil based you could rub vegetable oil into it allowing it to stay on as long as possible then brush, repeat as necessary. The dog will love all the attention, and his coat gets conditioned into the bargain.
Sorry, looking at all the advice, this seems to be the only remedy, short of clipping and scissors, but ask your vet.
