For a random process X consider the random vector defined by the values of X at times 0 ! U n;1 ! ::: ! U n;n ! 1 and the minimal values of X on each of the intervals between consecutive pairs of these times, where the U n;i are the order statistics of n independent uniform (0; 1) variables, independent of X . The joint law of this random vector is explicitly described when X is a Brownian motion. Corresponding results for Brownian bridge, excursion, and meander are deduced by appropriate conditioning. These descriptions yield numerous new identities involving the laws of these processes, and simplified proofs of various known results, including Aldous's characterization of the random tree constructed by sampling the excursion at n independent uniform times, Vervaat's transformation of Brownian bridge into Brownian excursion, and Denisov's decomposition of the Brownian motion at the time of its minimum into two independent Brownian meanders.
