From Calvin & Hobbes:
Calvin: Dad, how do people make babies?
Dad: Most people just go to Sears, buy the kit, and follow the assembly instructions.
Calvin: I came from SEARS??
Dad: No, YOU were a blue light special at KMart. Almost as good, and a lot cheaper.
Calvin: AAUUGHHH!
Cavins's Mom: Dear, what are you telling Calvin now?!
LOL
