It is somewhat common to see tracks in North American horse racing showcase a special guest racecaller for a dash or two. Although, Conan O’Brien of late-night talk show fame is not your average guest.

Santa Anita Park outside of Los Angeles, California has announced that O’Brien, 50, will be in the announcer’s booth this Friday (October 25) to call a thoroughbred dash.

O’Brien, who began his talk show career in 1993, is currently part of TBS’ late-night offerings with ‘Conan,’ which has been staple on the channel since 2010.
