The song was parodied, as "L.S. Bumblebee", as part of a satirical sketch on the Swinging London phenomenon in the Not Only ... But Also 1966 Christmas TV special,[148] which included a cameo appearance by Lennon.[149] Sung by comedians Peter Cook and Dudley Moore, both of whom are dressed in Indian clothing, the song evokes the seagull sounds of "Tomorrow Never Knows" through the presence of a bird squawking in the studio, and includes lyrics playing on the sensory contradictions of lines such as "Listen to the colour of your dreams" from the Beatles track.[148][150]

Rationale: Stimulation of serotonin 2A (5-HT2A) receptors by lysergic acid diethylamide (LSD) and related compounds such as psilocybin has previously been shown to increase primary process thinking - an ontologically and evolutionary early, implicit, associative, and automatic mode of thinking which is typically occurring during altered states of consciousness such as dreaming. However, it is still largely unknown whether LSD induces primary process thinking under placebo-controlled, standardized experimental conditions and whether these effects are related to subjective experience and 5-HT2A receptor activation. Therefore, this study aimed to test the hypotheses that LSD increases primary process thinking and that primary process thinking depends on 5-HT2A receptor activation and is related to subjective drug effects. Methods: Twenty-five healthy subjects performed an audio-recorded mental imagery task 7 h after drug administration during three drug conditions: placebo, LSD (100 mcg orally) and LSD together with the 5-HT2A receptor antagonist ketanserin (40 mg orally). The main outcome variable in this study was primary index (PI), a formal measure of primary process thinking in the imagery reports. State of consciousness was evaluated using the Altered State of Consciousness (5D-ASC) rating scale. Results: LSD, compared with placebo, significantly increased primary index ( p 2ff7e9595c
