Lex could ask Clark to get him precious objects from around the world (his collection seen in "Foundling"): the Venus de Milo's missing arms, Gainsborough's 'Yellow Boy', Beethoven's 'Tenth Symphony', Van Gogh's better self-portrait, the full figure 'Mona Lisa'. He could ask Clark to hit Superman with a kryptonite bullet (not knowing that Clark is Superman) or ask Lois to do it for Clark.
Whatever the tasks be, the important thing is... SQD is writing! Woohoo!!!!!
