I really should have known better

I bought weekend coffee* this morning. They gave me a free cup (which I needed due to exhausting dream and other things). As I walked in the office I said "Everything's coming up Milhouse!" However, I mentally acknowledged that last time I said that I promptly spilled the coffee on myself.

Guess what happened next?

*I use Trader Joe's beans during the week, and gourmet beans on weekends. It's a nice not-too-expensive treat that lets me look forward to using them.
