Smallville Season 10 Episode 15 – Fortune
“After Zatanna sends a magically spiked bottle of champagne to Clark and Lois for their bachelor/bachlorette parties, the gang blacks out after the toast and can’t remember anything about the night before. When Lois realizes she lost her engagement ring and drags Oliver back to the Fortune Casino, the two run into the owner Amos Fortune, who accuses them of stealing money from him. Meanwhile, Clark tells Chloe he has a memory of stealing an armored truck the night before.”
Looks like a funny episode!
