See You Later, Gladiator (Time Warp Trio #9)
By Jon Scieszka.
Description
One Minute the guys are wrestling around in Joe's room. The next minute "The Book" has transported them back to ancient Rome - and face-to-face with one big ol' gladiator. Luckily, Joe, Sam, and Fred, The Time Warp Trio, have seen enough professional wrestling to make it through gladiator school. - from Amzon
