You may play this game as a quick up-front game or even as a 4-person tournament. 2 contestants, each armed with a squirt gun, will take five paces and turn to duel. On each of their foreheads, you will have attached an Alka-seltzer tablet with double stick tape (possibly use big rubber bands if tape doesn’t work). They draw and shoot the water at each other, the first one to dissolve the tablet on the other's forehead wins. Use swim goggles for each to protect their eyes. The tablet will fizz and foam all over the place.

Have towels close by for clean-up. A cheesy western song (think Clint Eastwood or Lone Ranger) and some “cowboys” or “cowgirls” add to this one.

For this activity, you need ten non-permanent, washable ink pens. Have five guys each remove one shoe and one sock. They have three minutes to collect as many female signatures as possible on the soles of their feet. You might want to limit each girl to signing the foot of only three guys. 

Divide into two groups.

Form two lines. 

Each person gets a balloon that's inflated. 

The first person in each line is given instructions on what to do with their balloon (ex: dribble balloon to wall and back, kick ballon, balance baloon on foot, etc.). 

Once they have completed the task, they return to their starting point at the front of the line and sit on their balloon until it pops.  Only after it pops can the second person in line begin the assigned task that was given. 

Again, after they've completed the task, they return to their place in the line, and sit on their balloon until it pops. 

The first team to pop all its balloons, wins.

For this activity you need balloons (not inflated), two oversized pairs of sweat pants, two oversized sweatshirts and one needle. Break into two teams. Each team has two minutes to inflate and pass the balloons to a teammate who is wearing the oversized sweat pants and sweatshirt. This person stuffs the balloons into the oversized sweats. When the two minutes is up, a leader counts the balloons by popping them with a needle (carefully!) while the person is still “wearing” them. The team who is wearing the most balloons wins.
