What should Spence do to thank GGG for this victory?

GGG's destruction of Brook was so thorough, so devastating, that it was enough to produce 2 victories, one for himself and one for Spence Sorry Brook fans, but it's all over for the Tenerife Cruiser. Brook has gotten Margarito'd by the destructive fists of the kazakh beast. This is Pac-Margo all over again. That eye is seriously and permanently injured and everybody will thump it to **** from now on and stop Brook Brook's boxing days are numbered, the best he could do is going back to fighting bums and TBAs like he used to do, so he can squeeze a few checks before hangin' up the gloves for good So what should Spence do to thank GGG? send him a small check with part of the purse? some flowers and a thank you card? maybe invite him to dinner?
