This is great.
Lois thinking about Clark trying to pick her up, hilarious. Of course, he wouldn't.
On a side note, I remember reading an advertisement for a flirting crash course, complete with field training in Cologne during the carnival season.
Mix that with an article I read years ago, about a group of Americans wanting to do sightseeing on a Monday in Cologne (what could go wrong on a Monday?) and ended up in right in the middle of one of the biggest celebrations with several millions on the streets. I can see the plot bunny right there.
