A long, long time ago I found the perfect birthday card for my friend Dan. Dan, who you may remember as the “Gillis” in Snow, Snow & Gillis (2007), the groundbreaking paper entitled “The relationship between childhood attitude towards The Count and mathematical ability later in life: A thirty-year retrospective study.” I didn’t actually know when his birthday is, but figured that was a minor detail. Facebook would tell me, right? Yeah, Facebook told me today… that his birthday is tomorrow. He lives in Guelph, Ontario. So, since mailing the card is not an option, I’m going all Web 2.0 on ya – here’s your birthday card, Dan! Hope you have a good one!
