lol accually I know exactly what you are talking about I have smoked for about 3 years now and usually I am just kinda chilled and laid back but me and my friend luke smoked the other night before we went to this girls house to swim and on the way we picked up this one girl who was like "I have ginger-bread" and for some reason the ginger bread was hilarious I seriously cried I was laughing so hard at it and so was luke...omg it was bad...made complete asses of ourselfs in front of these girls but you might have gotten a different strain of weed than you are used to cause the stuff we smoked tasted different than what we usually got and I have to tell you we were three different kinds of fucked up...it was great though I think its great to laugh your ass off at nothing...you seriously feel so good afterwords and nothing can bring your high down at that moment...
