We show that for every m ∈ ℕ, there exists an n ∈ ℕ such that every embedding of the complete graph Kn in ℝ3 contains a link of two components whose linking number is at least m. Furthermore, there exists an r ∈ ℕ such that every embedding of Kr in ℝ3 contains a knot Q with |a2(Q)|≥ m, where a2(Q) denotes the second coefficient of the Conway polynomial of Q.
