This episode of The Big Bang Theory is absolutely hilarious. Sheldon feeling betrayed that Leonard is taking Penny to Switzerland on holiday on Valentines Day. Sheldon. Leonard really loves Penny and wants to give her a surprise by taking her her on holiday to Switzerland, but again Sheldon is just thinking about himself again, feels again and tells Leonard that he should be taking him on holiday to Switzerland. This episode is absolutely hilarious, I cracked up laughing a lot and Sheldon's deep throat singing was absolutely hilarious and made me laugh a lot.
