Perplex City: Season 1, Cards #017 - #020

Continuing my Perplex City solutations. Spoilers!

• #017 - Easy As...: You're kidding, right?
• #018 - Natal Name: The mother of my child solved this one a lot faster than if I Googled for it. 1910 is D, 1930 is B, 1970 is A, and 1990 is C. If I had done the Googling, I'd probably have ended up at the Top 10 Baby Names by Decade which concisely reveals the solution. There's dozens of these lists floatin' around.
• #019 - Magic Numbers: Oh lord - another memory from elementary school, where we'd revel in the magick of showing our mad calculator skills by making it talk to us. I remember 5318008 fondly. The answer is "hello" (0.7734 upside down). Elite.
• #020 - Barbeque: After thinking on this for a while and noticing a growing interest in Perplex City on #swhack, I broached the topic to Sean B. Palmer who pointed out my mental hurdle. Draw a table with 3 rows and 2 columns. If numbers represent burgers and letters sides of those burgers, place 1A, 1B, 2A, 2B, 3A, and 3C in each table cell, making sure that no one burger appears twice in a single row. With that visual aid, it becomes quite easy to solve, and a number of possibilities exist. Going by the entry dropdowns on the solution page, I did: Start (A: Top, B: Top, C: Off), After 5 Minutes (A: Bottom, B: Off, C: Top), After 10 Minutes (A: Cooked, B: Bottom, C: Bottom), After 15 Minutes (A: Cooked, B: Cooked, C: Cooked).
