Come on guys, the OP asked a simple question, and all he gets are humorous replies.
Rule -1468^e - i. Vomit on the playing surface
The table should be cleaned, preferably with bleach, an autoclave, and/or napalm, and the rack should be replayed as soon as both players are a)sober enough to bend down without backing out their dinner, or b)have had their stomachs pumped of all emitable matter. The non-chunk-blower will have the option of taking the break or making Ralphie McHurlerson break again. Repeat offenses should result in loss of match and permanent banishment from the establishment. Should Chuck Spewsalot return to said establishment on a later occasion and attempt to play pool, his opponent may nominate a "free cheap shot", and cover the table with a tarp or painting drop-cloth before racking, while laughing and exclaiming "I'm not taking any chances" or another equally glib remark. In the absence of a referee to judge the glibness of the remark, the benefit of the doubt will go to the remarker, and the remark will be considered a "burn."
Hope this helps.
