Bill & Ted's Most Excellent Adventures Vol. 2 by Evan Dorkin

Two lovable slackers continue their time-jumping, music-saving misadventures in a rollicking comic collection that sends them racing through history and the future, picking up famous figures, narrowly averting disasters, and creating anarchic, slapstick chaos wherever they go; equal parts affectionate pop-culture riffing and goofy heart, the stories emphasize their unshakable friendship and devotion to music amid rapid-fire gags and over-the-top set pieces.
