If you're a big Modern Family fan like I am, you will know that Dylan is allergic to one household product that actually quite a large percentage of Americans are allergic to as well without even knowing it:
Mayonnaise!
Dylan is one of my favorite characters on Modern Family, and I think him and Hayley are so sweet together.
How funny is it when he sings that totally inappropriate song to her in front of her entire family:
I don't think Dylan's allergy to mayonnaise crops up in too many episodes though, and I'm sure I don't have an allergy to it as I love the stuff lol!
