I'll try answering a few more, though some still have me boggled:
#29 Just one, the speaker
#30 He came/left on two different horses, named Monday and Friday, respectively
#31 Penguins and Polar Bears live in opposite hemispheres (Though, don't ask me which), so a polar bear wouldn't be eating any penguins
#34 Bungalows are one story, so presumeably there are no stairs
#36 You don't bury survivors (Typically speaking)
