Twelve Days of Christmas Swims?

I read your post last night and thought yuck I imagine a 12 days of Christmas workout to be awful. Got to Master's Class this morning and what do you think the workout on the board was? 

12 days of Christmas lol  

12 x 50 (1-4 c/u drill, 5-8 RTG, 9-12 swim)
11 x 50 don't remember the interval set
10 x 25
9 x 100 descend
8 x 75 as 25 swim/50 kick
7 x 50
6 x 50 as 25 swim/25 back
5 x 100 paddles and bouys but my shoulder was bothering me so I adjusted this to 100 for the 1st, next 3 were 50's, last was a 100 and all were paddles and fins instead of bouy.
4 x 100 descend
3 x 50 kick
2 x 100 all out 
1 x 200 swim down

I swam for years by myself at the Y during water volleyball class. I had to flip turn very carefully so I wouldn't splash the water walkers next to me and get their hair wet . I totally understand the challenge of swimming lonely. I really stalled joining the Master's group that formed last year at our pool because I had managed my swimming workouts myself for so long but it has really been good for me. They have motivated me to do more than I ever even thought I wanted to do lol. 

I asked coach if he had some kind of torture planned for New Years Eve. Yep - 100 100's. I think I'll be skipping that one!
