Shake a lot while being sure your penis is far from anything that might constrict the urethra, such as a waistband pressing against your dick.
i whip my penis around to get every last drop out. I also try to aim at the sides to reduce splashing. If I'm taking a shit and I'm peeing sitting down, I try to sit extra far back so my dick doesn't touch the side of the toilet and/or dip into the water so I don't drag any with me.
