From DC's Plop! #5 (1974)...
Easily one of the funniest gags about Clark Kent/Superman and Lois Lane ever told!
Though the writer of this short is unknown, the art is by long-time DC artist Murphy Anderson!
Trivia: The piece was actually conceived and illustrated as a one-pager, as shown in the original art below!

Note that the original panel six, showing Clark climbing back through the office window is omitted in the final version!
Blue pencil/marker didn't show up under the cameras that were used to shoot line art as film or photostats, so, while it looks a little tacky, it was common practice to mark corrections/alterations using them directly on original art!
(Nobody in those days was concerned about reselling original art to collectors/fans!)
The feature been reprinted twice since Plop!, but only in digest-sized comics, which muddy a lot of the detailed Sergio Aragones background art!
