Little help? w/FMK

Ever played Fuck, Marry, Kill? 

You state a trio of celebrities and decide whom you would fuck, whom you would marry, and whom you would kill. It’s a fun game for sitting around with friends because you have to rationalize your decisions. 

I’ve come up with a few that I can’t find a good third for—little help? 

1. David Byrne, Elvis Costello and ???

2. Neil DeGrasse Tyeson, Bill Nye and ???

3. Angela Carter, Margaret Atwood and ??? 

Any ideas or trios of your own to contribute? I’ll give you my answer and rationalization!
