The lie was...drumroll please...
I once threw a full water bottle at someone. I have never done such a thing, though the thought has crossed my mind before.
I did once sit under a table to eat Pringles, just so I could say I did. (Arbitrary Antics, anyone?) The people in the room just kinda looked at me, shrugged, and went back to eating their own food. I was expecting a more drastic reaction, honestly.
I did paint a mural for an event at my school.
Congrats to @Jacoby_Elderfun1, @Iliara_Mustardtop, @Jane_Gogglerubble, @Creel_Lenslook, @Creationary_Keyshimmy, @Jayanna_Larkcrash, and @Jayhawk_Greencape for thinking me crazy enough to eat Pringles under a table and for not believing me capable of such an atrocity as throwing a water bottle at someone.
