My first surprise t-bomb fight had to be with Squiggy, the Master of Evil.
However, I think the most memorable t-bomb fight was when Chuut, Agave, and I suddenly realized we were allied and alone in a bugged mission with no AI enemies left. The three of us never need much excuse to shoot at each other anyway, so this chance just couldn't be passed up.
Fortunately for me, Chuut had been a while from starbase and was low on mines. Truthfully, Agave was getting the better of me until I saw his weakness. I brought Agave to heel when I started t-bombing his PF's instead of his ship.
Agave: "No! NO! OK, I'll stop!"

It was nice knowing jus how expensive those little buggers were that campaign.
