My friend and I did this once...we got into a little trouble over it, but it was hilarious (at least to us) while we were doing it.

102. Find one of those huge plastic cages filled with stuffed animals. Pull them out, starting from the bottom, until you are surrounded by a pile of stuffed animals. Any employee that asks, you're looking for <insert animal type that you HAVEN'T found yet>. Fill the cage back up by throwing the animals back into the top. (You wouldn't believe how many times you'd miss the toss...those animals are bouncy!!) - Done
