Do you get weird like this?

whenever i get really tired i get delirious and start laughing at the stupidest things! its 4:25 AM right now and im just randomly on yahoo answers. and everytime i see an old question that has 0 answers i find it funny and it makes me laugh in real life. it just seems like everything is everything is funnier when you're tired. so i wanted to know if anyone else gets like this when they're tired, or it just me haha. thanks :)
