Just met some of the incoming freshman class. This time tomorrow we are going to be up to our armpits in unicorns!

She is such a unicorn! Last night she came to the apartment and yelled "Hey guys!" When she walked in. Then she started dancing around the room twirling and singing.

-Do you think she will be there tonight? I had better wear my lucky boxers in case she wants to talk to me.
-Dude, quit acting like a unicorn.
