Will it end?

As previously posted, our challenge is getting Maysen to stay in his bed and actually go to bed. Our nightly routine usually ends up with coming out of his room 49 times as he tries to dart unseen across the hall to the spare bedroom. Or, he'll spend the whole time ripping up his air vent and throwing things down the "tunnel" ... things include night light, or shoes, or cars, or diapers. Whatever he can find. The night usually ends with him passing out during whatever activity he was in the middle of. Case in point:

Last night was exceptionally exciting. He was up doing various activities for about 2hrs. We'd hear various crashes, smashes, laughing, rattling of the doorhandle, more laughing, grunting, and music. We've learned to just let him do whatever ... afterall, what kind of trouble can he get into? So, when we went to bed and went to check on him, you can imagine how hard it was not to bust out laughing when we saw this mess:

He piled toys, clean clothes out of his dresser, dirty clothes out of his basket, socks, shoes, animals, push toys, underneath this all are puzzles and books. Then he climbed up like "King of the Hill" and finally crashed. This pic was taken AFTER I put his right arm back into his pajamas. Otherwise that hummer was sticking straight out naked. Crazy...
