 Some of Liz's social problems stem from past slapstick events that left her with long-suppressed traumas and phobias.For instance, in "Reaganing", Liz reveals to Jack that she once ended up falling while wearing roller skates and with her underwear around her ankles, while covered by a Tom Jones poster (all while she was trying to find a bathroom to use in her house).When Jack learns she also freaked out when hearing a snippet of music in Las Vegas, she realizes that anything that reminds her of Tom Jones triggers her revulsion to sex.
