Comics Has Clark ever cheated on Lois?

[Miss Webb]

In action Comics Lana put her panties on the floor of Clark and Lois' apartment. She stayed there three days taking care of Clark while Lois was out of the country covering a story. Lois found the underwear. Fun ensues! It was a LOOOONG drive to Smalleville for Christmas...

Action 817, 818, 819. 822 and 823. Heh...

 

[The Englishman]

I don't think Supes would ever be unfaithful. Now Lois, on the other hand, has spent more than one occasion following Batman around...

Whens this happened, examples please....
