If Drake and Josh actually consumed raw beef, they would've gotten sick with salmonella or E. coli. Raw meat contains tons of bacteria when it is uncooked.
In Believe Me, Brother, Josh claimed that he was afraid of squirrels. Yet he tries to attach a note to one in this episode. Unless he got over his fear between episodes.
Megan throws lemonade on Drake and splashes him with it just because him and Josh made her miss Janie's birthday party and you can see that the juice is on his face and his shirt but when he says "don't touch the power saw" all the lemonade juice on him is gone, and he never had any lemonade stain on his shirt either.
