What's the difference between milk and my dad?
Nothing, I apparently am allergic to both because I never see either of them.
One time Michael Jackson had an allergic reaction from eating 12-year-old nuts.
I'm hertophobic -
aka I'm allergic to all straight guys.
There is a kid in my class who is allergic to peanuts. He says he's gay. He can't be though... he's allergic to nuts!
My friend died from an allergic reaction. He gave me an EpiPen while he was dying, so now I have something to remember him from.
