Tea Time

The "game over" usually refers to Starcraft. As for the "gumma", it's a local take on the word "shema", which means "what". The local language in my town occasionally got to a point of laziness where the sound "sh" was just too much trouble to pronounce, as I was explained.

Alcohol Matters

 

Please note that I have very little clue about brewing beer and alcohol in general, so the accuracy of this comic is a bit null. The idea is still there though, the same beer will taste different almost every time, and a few of my coworkers would joke saying "it depends on the kind of day they had at the brewery" that determines the quality.
