Rapper Nelly made sure Arsenio Hall honoured a baseball bet the pair made earlier this month (Oct13) by taking charge of the comedian's U.S. chat show on Monday night (21Oct13) and introducing the host as a rapper. The two friends bet each other their team would move on to baseball's World Series with Hall offering to perform Nelly's Country Grammar on his show if his beloved Los Angeles Dodgers were beaten in the National League Division Series by the rapper's St. Louis Cardinals. The Cardinals clinched their place in the finals on Friday night (18Oct13) and Nelly returned to the show on Monday to make sure Hall came through on the bet. Nelly said, "Ladies and gentlemen, because I won and he lost... Performing the hit classic, a song by all American traditions should be one of the biggest in your hearts, not only in your minds, here to perform the hit smash Country Grammar, please welcome your loser, Arsenio Hall." Hall stepped out wearing an Ozzie Smith Cardinals shirt and performed a segment from the hit.
