Post title is vague. Sorry.
Here is what I remember: John and Rodney get it on (either because of aliens or because of once in a lifetime chance yadda yadda); catch is that they are given this potion to drink to make them forget. One of them drinks his, but the other doesn't. And having the memories of their night of passion is driving that one nuts, so confrontation happens, and it's mcshep ever after.
I just can't remember which one drinks the stuff and forgets and which one doesn't and remembers. Ugh. It is not "One Night" or the one about the room that John and Rodney go into where their memories are wiped clean when they leave.
