Donnie is drunk 

One night when everybody was drinking  even you, Donnie got too drunk, which he didn’t want to, and everybody was surprised because he only had like maybe like three or four but he said that he would drink like about seven and then that’s when he was going to get tipsy but no Donnie: guys I think I drink too much Raph: oh my goodness, look at you you’re blushing so much! Mikey: he’s all flustered and you drunk (you and April were just talking and drinking) Leo: wow I didn’t expect this
