Soccer War

There was an actual Soccer War conflict. It was a war fought between Honduras and El Salvador, which was said to have been caused by El Salvador severing diplomatic relations with Honduras as a result of unsportsmanlike behaviour from the fans during the World Cup qualification play-offs between Honduras and El Salvador. However, it was more likely due to illegal immigration by the Salvadoreans into Honduras that got the ball rolling.

Also, this comic strip and its title is a reference to the Soccer Mode Event in World of Tanks. In Soccer Mode, the objective for the tanks is to blast the ball into the opposing side's goal. Like in real soccer, the side that has the highest score when time runs out wins. But if time runs out and the match ended in a draw, extra time will be added.

Daisy's Silk Bikini

To be fair, Daisy, the bikini you were wearing was similar to the one worn by Tatra from Magic Knight Rayearth.

This is what the bikini worn by Tatra looks like:

Also, nobody knows of any swimwear, especially bikinis that are made of silk or linen to begin with in real life. Maybe the outfit worn by Arabian Moon from Irem's Superior Soldiers/Perfect Soldiers may have something to do with it, given how skimpy it is.
