This comic is pretty funny. Now I also want to know if a duck's quack echoes or not. Moreover, the comic also justifies the posting of other pointless musings. For instance, yesterday I wondered why sunglasses are cool or chic, or stylish, whereas normal glasses, on the other hand, contribute to a nerdy, dorky, or uncool image? If anyone has an answer other than "I don't know", post it in the comments.
