People on Sargatanas did a Bikini Titan run a few weeks ago. I joined them, and we actually queued up the last DPS slot (so we had 2 tanks, 3 dps, 2 healers).

The DRG who joined us was confused, but quickly stripped his shirt and pants off to fit in, and we got him his relic. The rest of us had good fun.

Doing stuff at the lower end of ilevel requirement can be fun too :P
