It's been 25 years, forgive the poor soul.

ha ha, good one! :)

but my personal peeve is actually a little different: regardless of whether I'm part of a unique group or it works this way for everybody, the different parts of my brain remember the prank differently and at different rates of speed, so even after the prank is revealed/resolved, the part of my brain that flinches keeps remembering the lie, not the truth. Like, my gf recently April fools' pranked me that my favorite restaurant was going to close soon. Now, every time I pass the place or think of it it, I immediately think "and I've got to go there soon before it closes" even though immediately after that I think "oh, no, that was a prank" I still have the surge of emotion. In terms of the prank, I get it, my reaction was funny. But in terms of time wasted, it's worse because it's Attention Deficit time, and I know I continue to find it sooo irritating well beyond the momentary pleasure she got out of it.
