What's the biggest prank you've ever pulled?

Oh man! that is so funny! What a great joke.

This my first post so please be kind…

Pranks I (vaguely) remember from university.

  1. Members of the moutaineering club broke into a very high security prison.

  2. A very famous liner was set adrift from it’s moorings during rag week.

  3. When a student went on vacation, all the furniture from his room was removed. Turfing was placed on the floor, and a sheep put into the room (just before his return).

  4. When a student went on vacation, a mini (car) was dissambled and reassembled in his room.

Two of the above pranks I can actually verify. However, two I heard of second hand and may just be urban myths.
