No, no...
do something like put the rubber hair caps on the head (like normal) and be in swimsuits and do like sincronized swimming on the gym floor (dancing around) playing cheesy music. Spelling the word S-W-I-M space T-E-A-M or something like that...promoting the swim team/and unity.
Or play Maro-Polo with the rubber hair caps over thier eyes. That'd be pretty funny.
Hmmm I'll keep thinking.
