Mavericks point guard Steve Nash appeared Wednesday on Letterman's Late Show, taking advantage of a break in the NBA playoff schedule to crack wise with CBS' All-Star prankster in the famously cold Ed Sullivan Theater.

Nash, once a tabloid target for his liaisons with Elizabeth Hurley and former Spice Girl Geri Halliwell, is just the second NBA player to guest on Letterman this year. Former Maverick Jason Kidd, now playing for New Jersey, was the other.

Letterman is known for getting a little ornery with some guests. But Nash said the Late Show host was pretty tame, or "pretty middle of the road," in the guard's words.
