This is what I do to Jacob. I give him a cold glare, if he doesn't stop I grab something hard and threaten him with it, if he still don't listen I smack him with it. Usually once I toy with him by theatening it stops.
Lately my brother has gotten to be more Disgusting then EVER, he thinks it's funny to not bathe for weeks, he thinks its funny to go into a stream half naked by a Highway (Sadly I saw him do it. I could see people laughing) And he always is making up these Sick jokes ><
