From Jessen on Twitter;
"Bully Ray came out suddenly and got Terry Funk and Tommy Dreamer with some major blows He challenged Tommy Dreamer to a match on December 30th TNA PPV "School" to an £Old School£ Street Fight with Falld Count Anywhere stipulations. After, Devon joined Bully Ray and got Dreamer with the 3D. The Sandman then came out and caned the Dudleys but the Dudleys took control and declared House of Hardcore theirs."
