Ones I got wrong:
#4 Campbells soup can one was tough (I only missed gold)
#10 FM dial I thought 88.1 not 88
#12 No smoking sign, well I missed a 50/50 shot (who pays ANY attention to "No Smoking" signs with this crowd anyway?)
#19 ARGH, I REALLY gotta read more!
#22 I never liked Snow White and the 7 dwarfs
#26 One dollar bill question (geez I'm an idiot)
