This is an old one, but done right can be very funny. The best thing to wait till the Stag, having shower and steal all his belongings out the room. Replace said belongings, with at ridiculous costume. He is left with a conundrum, if he wants to go out he will have war the costume.
Firstly, this prank should probably only be done if the groom isn’t getting married for a month or so after the Stag. This is to insure the tan will wash off. This one can be done two different way. The first is add very cheap very strong fake tan to groom’s shower gel. As he washes himself he will also tanning himself. Fair play to him. This may not be as effective as he may see the tan in that shower gel. The second way to buy spray on tan and apply generously to Stag’s face as sleeps, will give nice healthy umpa-lumpa glow!
This is a prank that can be great fun for everyone involved, except the Stag. For this you will need to have a two-night stag planned but tell the stag it is only for one-night. The day before these Stag believes is group from the stag party, wearing balaclavas, kidnap him! A van is preferable but your discretion. Without talking, drive the Stag around for 20-30 minutes. If you really want to go all out, playing voice recording of foreign language being spoken would nice touch!
This one is great, it’s simple, and its definitely our favourite here at TheStag.ie. Have t-shirt made up with picture of stag or even just “Stag on tour”. Buy UV paint and write message on back for t-shirt. Suggestions could “I just Farted”, “My mammy Says I’m Great”, etc. The Stag will believe got off lightly only have wear t-shirt, however every time walks UV light the message will appear.
