From looking out the window at work the basic technique appears to be:
- wait for other seagull to stand on ledge of very tall building
- sneak up and insert seagull willy
- flap like a maniac. Not so hard that you take off though.
- repeat all fucking day. if you get tired just hang around squawking like a noisy prick for a bit.
*herring gull, obviously, but odd socks mustard bread roll innit
