Archie's Pal Jughead Comics / Jughead (1949-1987) #199

Plot

There's a "Switch Dance" where the boys have to ask the girls, and Archie winds up making a date with Betty, Veronica and Midge all at once, to Jughead's horror: "I've seen you date two, by mistake -- but three!?" Jughead is even more horrified when Archie treats the triple-date as the ultimate challenge and tries to actually date all three girls without any of them finding out.
